Heart "hitched"?

When I come to my senses, I feel lucky and scared.

The heart suddenly stopped beating.

What the hell is going on?

What happened to the sudden "thump" of the heart?

The beating of a normal heart is regular, and the interval between heartbeats is basically equal. If the heart suddenly "thumped", it may be because the heart contracted ahead of time before the interval, making the heart beat prematurely.

Premature beat is a common clinical symptom, which has a wide range of diseases. Both normal people and patients with heart disease can have premature beats, and the incidence of premature beats increases with age.

Why do you have premature beats?

The human heart is a powerful muscle pump. It has left and right sides inside, and each side has two atrioventricular cavities.

The upper part is called atrium, and the lower part is called ventricle. The atrium can store blood, and the ventricle is responsible for pumping blood out of the heart.

In the upper right corner of our right atrium, there is a great man named "sinoatrial node", which can send out normal heartbeat signals and transmit them to all myocardium. He is a general commander!

But it’s hard to do this job, because there are always some "troublemakers" in the heart who want to usurp power and seize position, and their appearance will make the heartbeat signal abnormal, that is, premature beats.

If the abnormal signal originates from the atrium, we call it "atrial premature beat" (referred to as atrial premature beat), and if it originates from the ventricle, it is called "ventricular premature beat" (referred to as ventricular premature beat). If it is located at the junction, it is atrioventricular junctional premature beat.

Is premature beat a disease or a symptom? Is it life-threatening?

Premature beat is a disease, the symptom is that the heart suddenly "hitches". Most premature beats are benign, and the greatest harm to patients is psychological, which affects the quality of life.

Premature beat refers to the heart beat caused by premature impulse from ectopic pacemaker, which is the most common arrhythmia. Most premature beats are benign, although they will upset patients, but not fatal.

The incidence of malignant premature beats is very low. So don’t panic all day because of premature beats, there is no need to panic too much. It is suggested that patients should have an electrocardiogram, and doctors should judge the nature of premature beats. At present, it cannot be cured with drugs, but it can be controlled. Severe cases can be cured by catheter ablation.

How to stabilize the "jumping" heart?

Life and rest, eating habits, exercise intensity, etc., may affect the heartbeat, and daily adjustments can be made from these aspects.

01

Change the unhealthy lifestyle

Develop a regular routine, and try not to stay up late unless necessary; Quit smoking and drinking, drink less strong tea, especially before going to bed; Regularly defecate and keep defecation unobstructed.

Don’t be greedy for cold, don’t blow directly into the air conditioner, take a cold bath, or drink iced drinks.

02

Stay optimistic.

Mental stress, excessive psychological pressure, etc. may cause abnormal heartbeat, so we should actively adjust negative emotions to avoid excessive excitement or sadness.

If the heart rate is too high due to nervousness and emotional excitement, you can gradually restore calm by listening to music and meditation.

03

Strengthen exercise

Regular exercise, with appropriate exercise intensity, will exercise the cardiopulmonary function. The scientific exercise frequency is 3~5 times a week, 20~60 minutes each time, excluding warm-up and finishing exercise after the end. Recommended walking, swimming, Tai Ji Chuan and other projects.

Generally speaking, it is appropriate that the heart rate during exercise is about 20 times faster than that at rest. The internationally accepted formula is:

Exercise heart rate = 170-age

For frail and older people, exercise heart rate = (170-age) ×0.9.

04

Control weight

Obesity will increase the burden on the heart, and obese people should maintain a suitable weight through physical exercise and diet adjustment.

Body mass index [BMI= the square of weight (kg)/height (m)] is an important method to evaluate the degree of obesity. In China, it is generally considered that BMI≥24 is overweight and BMI≥28 is obese.

05

Reasonable diet

Develop a good habit of chewing slowly, and don’t be too hungry and full; Increase the intake of fresh fruits, vegetables and fish, eat less irritating food, reduce salt and oil and eat less fast food.

pay attention to

If relatives and friends around you suddenly get sick because of abnormal heartbeat, you should master some treatment methods:

Tachycardia: let him rest immediately, cough hard, lean back as far as possible or bend forward, which can stimulate vagus nerve and terminate some tachycardia; Tapping the precordial area several times is helpful to help the heart to cardioversion;

Bradycardia: you can take one piece of atropine and call the emergency number at the same time.

General Secretary of the Supreme Leader, in a collective conversation with the members of the new leadership team of the Central Committee of the Communist Youth League, stressed that only when young people have ideals, dare to take responsibility, endure hardships and are willing to struggle can China youth have strength and the development of the party and the country be full of hope. The great changes in the world in the past century have accelerated the evolution, and unstable, uncertain and unpredictable factors have increased. It is a long way to go to build a socialist modern country in an all-round way and realize the great rejuvenation of the Chinese nation. Every generation has its own long March, and every generation should take its own long March. The General Secretary of the Supreme Leader stressed that the vast number of young people "should keep in mind the Party’s teachings, be determined to rejuvenate the nation, live up to their youth, live up to the times, live up to the people, run hard on the track of youth, and strive to run out of the best achievements of contemporary youth". In the new era and new journey, the majority of young people should give full play to the characteristics and spirit of having ideals, daring to take responsibility, being able to bear hardships and being willing to struggle, strive to be new people of the times who are worthy of the heavy responsibility of national rejuvenation, make strenuous efforts and forge ahead bravely in the torrent of the times to realize the great rejuvenation of the Chinese nation, and run out of the best achievements of contemporary youth on the track of youth.

　　Have ideals

　　 The ideals and beliefs of young people are related to the future of the country. Ideal guides the direction of life, and faith determines the success or failure of career. Young people’s lofty ideals and firm beliefs are the invincible driving force for a country and a nation. The firmness of ideals and beliefs comes from the sobriety and firmness in thought and theory. General Secretary of the Supreme Leader pointed out: "Only when you are sober in theory can you be firm in politics. A firm ideal and belief must be based on a profound understanding of Marxism and a profound grasp of historical laws. " In the new era, young people in China are firm in their ideals. They should adhere to the guidance of scientific theory and constantly strengthen the armed forces of Marxist theory. Theoretical learning is a process of constant learning, constant understanding and constant innovation. The majority of young people must cultivate theoretical study as a living habit and spiritual pursuit, adhere to the principle of understanding the original text by reading the original text, persist in thinking more, learn deeply and thoroughly, and comprehensively study and understand the scientific system, essence and practical requirements of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, so as to achieve overall mastery and mastery. The ultimate goal of theoretical study lies in application. We should vigorously carry forward the Marxist style of study, adhere to the problem orientation, adhere to the unity of knowing and doing, apply what we have learned, improve theoretical literacy, strengthen our ideals and beliefs, enhance our ability and skills in the process of deep study, and take establishing correct ideals and firm beliefs as the foundation of our foundation, and strive to grow into aspiring young people expected by the party, the country and the people.

　　Dare to take responsibility

　　 Young people dare to take responsibility, which is the hope of a country and a nation’s prosperity. General Secretary of the Supreme Leader pointed out: "The future of the country, the destiny of the nation and the happiness of the people are the important tasks that contemporary China youth must and will bear." In the new era, young people in China should shoulder the heavy responsibility entrusted by the times, always bear in mind their responsibilities to the party, the country, the nation and the people, so as to be aware of their responsibilities, take responsibility for themselves and carry out their duties. In the ten years of the new era, the party and the country have made remarkable achievements in various undertakings, the people’s living standards have improved significantly, a well-off society has been built in an all-round way on the land of China, and the problem of absolute poverty has been solved historically. At present, the great changes in the world that have never happened in a century have accelerated evolution, and the great rejuvenation of the Chinese nation has entered a critical period. The risks and challenges we face have increased significantly, and there are still many difficulties and problems in the development process. We need to show the spirit of "meeting the brave in the narrow road" and carry forward the spirit of "the more difficult and dangerous, the more forward". With the spirit of "newborn calves are not afraid of tigers", young people should be brave in being pioneers, shouldering heavy burdens, going deep into the grassroots and front line, not afraid of risks and facing difficulties, rushing out and coping with difficulties when the party and the people need them most, always maintaining tenacious fighting spirit and tenacious will, constantly improving their ability and skills, bravely standing at the forefront of the times and striving to be pioneers of the times.

　　Can bear hardships

　　 Being fearless and able to endure hardships is what young people in China should look like in the new era. In his reply to the students in the Science and Technology Academy of China Agricultural University, General Secretary of the Supreme Leader highly affirmed the spirit of "asking for hardships" of young people in China in the new era, which is not only a full affirmation of young people in China in the new era, but also an ardent expectation for young people in China in the new era. "Suffering hardships" is the only way for young people to grow into talents, which has rich connotation of the times and practical requirements. With the change and development of the times, the internal requirements and external forms of "hardship" are constantly changing. General Secretary of the Supreme Leader pointed out: "In youth, if you choose hardship, you choose harvest, and if you choose dedication, you choose nobility." Today, we have achieved a well-off society in an all-round way. "Suffering" is no longer a material suffering from lack of clothing and food, nor is it a physical hardship to starve one’s body. What we emphasize is "suffering", which is more reflected in scientific and technological research posts. In order to solve the technical problem of "getting stuck", we are willing to sit on the bench; It means that in the front line of emergency rescue and disaster relief, for the safety of people’s lives and property, they are not afraid of sacrifice; It means that in the main battlefield of rural revitalization, in order to accelerate the modernization of agriculture and rural areas, we work hard and forget ourselves; It means that in defending the frontier of the motherland, for the sake of national security and national interests, we should be fearless and guard with our heart … "Suffering hardships" should become an active behavior and dare to be good at "asking for it". In the new era, young people in China should strengthen their consciousness of "wanting to suffer hardships", abandon their arrogance, take the initiative to take exercise in a difficult environment and take the initiative to undertake urgent and dangerous tasks; Strengthen the courage to "dare to suffer hardships",Persevere in the face of difficulties, challenges and setbacks, and dare to take the lead in the face of urgent, dangerous and difficult tasks; Hone the quality of "being able to bear hardships", be brave to go to the main battlefield of economic construction, the new field of social construction, the forefront of scientific and technological innovation, the front line of key projects, and the melting pot of grassroots practice, and experience the great ambition, indomitable will and optimistic spirit of serving the motherland in hardship.

　　Willing to struggle

　　 "I am confident that if I live for 200 years, I will be hit by water for three thousand miles." General Secretary of the Supreme Leader has earnestly enjoined the young people of China in the new era to be brave in their struggle. The mission of national rejuvenation should be realized by struggle, and the ideal sail of life should be raised by struggle. In the new era, young people in China should regard struggle as the brightest background of their youth, take it as their responsibility to realize the great rejuvenation of the Chinese nation, integrate their youth and dreams into the national and ethnic undertakings, and strive passionately on the track of realizing national rejuvenation. Stand firm on the people’s stand and bloom the flowers of youth in the cause of serving and benefiting the people.

According to Reuters, Associated Press and other foreign media reports on April 17th, U.S. President Biden is expected to officially announce that he will triple the current aluminum tariff on Huagang in a speech to steel workers in Pittsburgh, which is known as the "steel capital" later that day.

Pennsylvania, where Pittsburgh is located, is one of the "battleground states" in the American election. This move coincides with the warming of the US election campaign. Many media associations have analyzed that Biden seems to "emulate" Trump’s "old trick" and consolidate blue-collar votes through protectionist policies. However, according to the White House, steel imports from China only account for 0.6% of the total steel demand in the United States.

Earlier this month, Bloomberg reported that China did not seek to produce more steel than long-term demand, and should not be responsible for the weak steel prices in the United States. The Associated Press warned on the 17th that rashly raising tariffs may bring economic risks to the United States, which is already facing the inflation crisis in Qualcomm, and may also affect other downstream industries.

On the 17th, the White House website published a so-called "list of facts", claiming that new "historic actions" will be taken to protect American steel manufacturing and shipbuilding industries from China’s "unfair behavior". The first one is to call on the Office of the United States Trade Representative (USTR) to consider "tripling" the current "Article 301" tariff rate for China steel and aluminum products.

Biden’s proposed tariff increase was originally imposed by former President Trump under Article 301. "Section 301" refers to Section 301 of the US Trade Act of 1974, which authorizes the US Trade Representative to initiate an investigation into "unreasonable or unfair trade practices" of other countries, and may suggest the US President to impose unilateral sanctions after the investigation. The White House said that at present, the average tariff imposed by the United States on some steel and aluminum products is 7.5%. According to a US government official, Biden plans to increase this figure to 25%.

According to "Article 301", four years after the first collection of tariffs, the procedures for reviewing these tariffs must be carried out. The review led by Dai Qi, the current trade representative, should have ended by the end of 2023, but it has not been completed so far and has been urged by some business groups. According to a report by CNN on the 17th, a senior Biden administration official said that it is expected that the review will be completed "soon" and Biden may take actions to "(strengthen) the effectiveness of tariffs" according to the review results.

It is reported that Biden will visit the largest trade union in North America in Pittsburgh, Pennsylvania on the 17th — — United steelworkers union (USW) headquarters and announced the above measures in a speech. Located in the "rust belt", Pennsylvania is the main base of traditional industries such as coal, steel and mechanical and electrical products in the United States, and USW represents nearly one million workers in the steel industry in North America. Neither the Democratic Party nor the Republican Party can ignore this powerful force.

Biden’s high-profile approach is part of his campaign for the November presidential election in Pennsylvania, where he is expected to launch a three-day canvassing campaign from April 16 to 18. Pennsylvania is regarded as one of the six key swing states. In the 2020 general election, Biden narrowly defeated Trump here. Biden himself was born in scranton, northeastern Pennsylvania. The US media said that he visited the state more times than any other state.

"The president understands that we must invest in American manufacturing." When briefing the media, Lael Brainard, director of the White House National Economic Council (NEC), claimed that "overcapacity" in China’s steel industry "poses a serious risk" to the future of the US steel and aluminum industry, and Biden’s appeal would protect the US manufacturing industry from the so-called China subsidies and policies.

In addition to raising tariffs, the White House announced on the 17th that it would further cooperate with Mexico to ensure that enterprises and manufacturers in China and other countries could not evade tariffs by transporting steel or aluminum products to a third country and then exporting them to the US market. In addition, the White House also responded to a petition filed by five major trade unions, including USW, last month, saying that the US Trade Representative is investigating China’s so-called "unfair trade practices" in maritime, logistics and shipbuilding industries.

Although the White House tried to explain to the US media that their tariff increase is different from Trump’s, it is "strategic, balanced and targeted" and more to "protect" the US manufacturing industry, but many US media have mentioned in their reports that this move may bring major economic risks to the United States, and economic problems have dragged down Biden’s political fate.

The US Consumer News and Business Channel (CNBC) said that critics believe that increasing tariffs will only be counterproductive, raising US consumer prices and exacerbating inflation. The Associated Press pointed out that after raising tariffs, the prices of steel and aluminum may rise, which may increase the cost of automobiles, building materials and other major commodities for American consumers. Washington post bluntly said that this measure against the steel industry may cheer Biden’s trade union audience, but it may also increase the cost of other industries that use steel, which employ far more workers.

In the view of the Associated Press, Biden’s turn to trade protectionism policy on the eve of the election is exactly the same as that of his predecessor and rival Trump. CNBC said that Biden has been stepping up his remarks about China’s economic policy, and so has Trump, who once said that he would consider imposing a 60% tariff on all goods imported from China. An external analysis by Oxford Economic Research Institute shows that the implementation of Trump’s proposed tariffs may damage the overall economy of the United States.

The US media has noticed that recently, American officials have been "complaining" about China’s manufacturing overcapacity more and more frequently. Yellen, the finance minister who visited China earlier this month, repeatedly mentioned and hyped the problem of "overcapacity" in China’s traditional manufacturing and new energy industries, claiming that this "distorted the global market".

In this regard, Bloomberg published an article on April 3rd, pointing out that China did not seek to produce steel beyond the long-term demand. Compared with its output, it is not even a particularly large steel exporter, and China should not be responsible for the weak steel prices in the United States. According to the White House in its "list of facts", steel imports from China only account for 0.6% of the total steel demand in the United States.

The article also stated that the tariffs imposed by the United States on China many years ago did not prevent the reduction of jobs in its domestic metal manufacturing industry. With the United States entering the post-industrial and service-oriented development stage, American steel consumption has peaked and is declining. In the past decade, misleading steel protectionism has only increased the cost of other areas of the American economy and reduced its competitiveness.

China Iron and Steel Industry Association and China Nonferrous Metals Industry Association said in a statement earlier that the core goal of China’s iron and steel industry and aluminum industry has always been to meet domestic demand and achieve high-quality development. China’s exports of steel and aluminum products to the United States account for a small proportion. The trade and cooperation between the two countries’ industries are based on the strong complementarity between China and the United States, and are completely based on the principle of fair marketization, which not only does not harm the United States, but also benefits downstream customers and promotes the development of related fields in the United States.

According to the statement, China’s steel and aluminum industries began to eliminate backward production capacity in 2010, and implemented supply-side structural reforms in 2016, greatly reducing the production capacity of steel and electrolytic aluminum. Up to now, the steel and aluminum industry in China has been strictly controlling the new production capacity, and at the same time, it has set up a ceiling for production capacity. The reform has achieved remarkable results and effectively promoted the healthy and sustainable development of the steel and aluminum industry in the world.

As for the issue of the US levying tariffs on China, China has also responded more than once. Mao Ning, the Foreign Ministry of China, once pointed out that the essence of Sino-US economic and trade cooperation is mutual benefit and win-win. There is no winner in trade wars and tariff war, and artificial restrictions or protectionism will only interfere with normal trade exchanges and the stability of the production and supply chain, which is not in the interest of either party. The United States should earnestly respect the principles of market economy and international trade rules and create a good environment for Sino-US economic and trade cooperation, not the other way around.

The national software WeChat once again attracted attention.

On February 3, "WeChat mobile phone number can register two accounts" rushed to the hot search. What do you mean, "WeChat mobile phone number can register two accounts"? Simple understanding is the "trumpet" of WeChat. If you only have one mobile phone number, but want to register two WeChat accounts, it was not possible before, but now you can register two micro signals with one mobile phone number.

For many WeChat users, with more and more WeChat friends, all kinds of friends are concentrated in a micro-signal, which is inconvenient to manage, so many users work under one number and live under one number. As early as 2018, the new function released by WeChat has the function of switching login accounts. However, switching accounts means that you need two mobile phone numbers to register two WeChat accounts.

Many WeChat users feel that this function is a real "epic update". How to register WeChat "trumpet"? What will happen to the new and old WeChat accounts after registration? What should I pay attention to when using it? What convenience can "trumpet" bring?

To register WeChat trumpet, you can do it in WeChat-Me-Settings. Click Switch Account in Settings, and the currently used WeChat account and the prompt of "Add Account" will appear on the page. After clicking Add Account-Register a new account, you can choose whether to register with the new mobile phone number or use the current WeChat mobile phone number to assist in registration.

Of course, the WeChat "trumpet" is registered with the current WeChat mobile phone number. Many netizens said that the WeChat "trumpet" could not be opened for various reasons, for example, the WeChat account without WeChat payment could not be opened, and some netizens encountered the prompt that "there are many people trying to register at present, so you can try again later" when registering. In short, I feel that the current registration function is not stable.

Of course, not all WeChat users can register WeChat "trumpet". There is a certain threshold. According to the official announcement, the conditions for opening WeChat "trumpet" include that the current WeChat account has been bound with the mobile phone number, WeChat payment has been opened, and the registration time has exceeded a certain period of time, and the current account has no security risks.

The step of "auxiliary registration through the current WeChat mobile phone number" is not complicated. According to the prompt, security verification is carried out, including sending a short message according to the prompt, and the user is required to send a short message with the specified content to a specified number with the current WeChat mobile phone number. In fact, the whole registration process is basically this step, and then we need to set the micro signal and login password.

When logging in to this "trumpet" for the first time, WeChat will prompt you to create a micro signal. Be sure to remember that the micro-signal should be set to be easy to remember, because after the registration is completed, the micro-signal "trumpet" will appear in the list of "switching accounts". If you choose to log in with "trumpet", you can’t log in with your mobile phone number as before, but log in by "micro-signal+password". Although you can get it back if you forget the micro-signal, it will be more troublesome.

There is not much difference between using WeChat "trumpet" and using the old WeChat account. The most basic chat, address book and circle of friends are almost the same. There is no data sharing between the WeChat trumpet and the original WeChat account. The friends in the WeChat account are still in the original WeChat account, and the friends in the WeChat trumpet should be added again, which is equivalent to opening a brand-new WeChat account.

However, because there is no real-name authentication, the function of WeChat payment cannot be used in the "trumpet". If you want to open WeChat payment, you need to re-authenticate your real name, that is, you need a mobile phone number for registration authentication.

You don’t need a mobile phone number to register a new WeChat. The WeChat "trumpet" is like a "compressed version". Besides separating work and life to a certain extent, it can also be used by children. Before registering a WeChat account for a child, it was necessary to "consume" a parent’s mobile phone number or set up a new one, which would also bring some inconvenience. Opening a "trumpet" can solve this problem.

Tips：

About WeChat "trumpet", you need to know these.

Q: How many WeChat accounts can a WeChat account assist in registering?

A：What we call "trumpet" is actually to register a new account with an authenticated WeChat account. Each WeChat account can only register one WeChat account, that is, there can only be one trumpet. If you want to register more than one "trumpet", the page will prompt "It is temporarily impossible to register a new micro-signal".

Q: How to let others search for their own "trumpet"?

A：When adding a friend, just tell the other party your own "small" micro signal. If you tell the other party your mobile phone number, the other party will find the original WeChat account.

Q: What should I do if I want to use WeChat payment on the trumpet?

A：You need to bind a new mobile phone number to "trumpet", but it must be a mobile phone number that is not bound to other WeChat, which is equivalent to making "trumpet" an independent WeChat account. Specific operations can be in the "trumpet" I-Settings-account and security-mobile phone number in the binding of a new mobile phone number, go through the identity authentication and other real-name processes.

Q: If you forget the micro-signal and password of the trumpet, how can you get it back?

A: When registering a trumpet, you need to use a mobile phone number to complete a short message verification. This is to ensure the security of the registered account, and this mobile phone number is only used for micro-signal security verification in registration. If there is no "trumpet" bound to the new mobile phone number, you can perform security operations such as login verification and password recovery verification through the old account. If the "trumpet" has been bound with a new mobile phone number, just log in or retrieve the password through the mobile phone verification code.

Q: Many users find it troublesome to switch WeChat accounts. Can I log in to two accounts at the same time after opening the "trumpet"?

A：You think too much about this question, and it is still not possible at present. The two WeChat accounts are relatively independent.

You can have a look

Don’t miss these new WeChat features.

In addition to registering WeChat "trumpet", if your WeChat is upgraded to the latest version 8.0.32, I believe you will find many changes, which is also the first updated version of WeChat in 2023.

1. Add a message prompt when refusing to call.

When I received a voice or video call from WeChat at an inconvenient time, all I could do before was to "refuse". After the rejection, if you want to send a message to the other party, in addition to the reminder of "Call Rejected", a "Send Message" button is added on the message banner of voice or video. Click "Send Message", the page will automatically jump to the quick chat interface, and you can send a message directly to the other party, eliminating the step of going to the friend list to find friends.

2. Support indoor map function

Many "road idiots" have the experience of getting lost in the shopping mall. If you make an appointment to meet your friends in the shopping mall, but you just can’t find the location that your friends said, you can try the indoor map function of WeChat. When sending location or real-time location to friends, the new version can not only send accurate floor location, but also specific to a store. However, at present, only some regions and large supermarkets support this function. If the coverage is getting wider and wider, this function is still very practical.

3. Video playback is scalable

Watching photos on WeChat can be zoomed, but watching videos can’t. Now watching videos and watching photos have "equal treatment". After selecting a video, click "Play Full Screen", and you can pinch or double-click the screen with your two fingers. The video screen will be enlarged or reduced, similar to zooming photos.

4. Customize chat history cleaning

Chat record is the "treasure" of WeChat, which accounts for most of the chat record in the memory of the mobile phone, and it is very tangled every time it is deleted. Before, you can choose to clean up the chat history in the time range of all time, three months ago and one year ago. Now the time range you can choose is more detailed, and now the option of "custom time" has been added to the filter criteria. By "start date" and "end date", you can clean up the chat records of a certain day, or you can freely choose to clean up the records of a certain time period, so that you can delete them more accurately and greatly improve the convenience.
