The speed of heartbeat is related to the length of life. How much is the heart rate?
"Hey, come on, do you have someone to call 120?" Ms. Zhang shouted anxiously.
It turned out that Ms. Zhang and her best friend Ms. Li went out for a outing in the park. Who knows, walking, Ms. Li suddenly fainted in the dark, which scared Ms. Zhang. With the help of passers-by, Ms. Li was rushed to hospital.
Through ECG examination, the doctor found that Ms. Li's heart rate was very slow, only 38 beats / min. finally, it was diagnosed as third degree atrioventricular block, resulting in slow heart rate and fainting.
After that, the doctor learned that Ms. Li actually found her heart rate was slow when she had a physical examination one year ago. The doctor suggested her to have a further examination.
However, Ms. Li did not feel at ease, and even thought it was a good thing because she heard people say that "a slow heartbeat leads to a longer life". Even if she occasionally had dizziness, she only thought it was hypoglycemia. She didn't realize the seriousness of the problem until she fainted.
1、 The speed of heartbeat is related to the length of life. How much longer is the heartbeat?
In fact, there has always been a dispute about the relationship between the speed of the heartbeat and the length of life. How much longer is the heartbeat?
Generally, when adults are in a quiet state, the heart rate fluctuates between 60 and 100 beats / min, with an average of 75 beats / min. If it exceeds 100 beats / min, it is considered as tachycardia; if it is lower than 60 beats / min, it is considered as bradycardia.
Is it better to have a fast heartbeat or a slow heartbeat? A study by Taiwan's "Health Research Institute" gave the answer.
The research was carried out by the team led by Professor Wen Qibang. After collecting and analyzing the data of nearly 2 million physical examinations, it was finally found that the heart rate of healthy people was 60-100 beats / min, and with the increase of heart rate, the life expectancy would be shortened, as follows:
The heart rate is 70-80 beats / min, and the life expectancy is shortened by 3 years on average;
80 ~ 90 times / min, with a short life expectancy of 5 years;
The heart rate is 90-100 beats / min, and the life expectancy is 8 years shorter.
The explanation given by the doctor is: tachycardia can obviously increase the burden of the heart and may further affect the life span.
In addition, scientists have also found that animals with slower heartbeat live longer. For example, small mice have a heart rate of 500 beats per minute, and the average life span is about 3 years; Cats and dogs 100 times / minute, with a life span of about ten years; Whales, on the other hand, have a heart rate of 15-20 beats per minute and a life span of more than 80 years.
Does that mean that the slower the heartbeat, the better? This statement is not comprehensive. Whether the heartbeat is fast or slow depends on the individual.
Generally speaking, in healthy adults, within the normal heart rate range, the slower the heart rate, the better; However, for patients with hypertension and coronary heart disease, it is most beneficial for patients to control their condition if their heart rate is controlled within the target value.
In other words, too fast and too slow heartbeat may harm the body, so it is best to keep a normal heart rate range. If the heart beats slowly within the normal range of 60-100 times per minute, the life will be relatively long.
2、 The heartbeat is too fast or too slow, or it indicates the coming of disease
Sometimes the heartbeat is too fast or too slow, which may be caused by some diseases. At this time, we must pay attention to differentiation to avoid delaying treatment.
1. Atrial fibrillation
Atrial fibrillation can be caused by a variety of reasons, such as hypertension, diabetes, coronary heart disease, smoking and alcohol abuse. When this happens, the main manifestation is irregular heartbeat, and the patient may have palpitation, chest tightness, shortness of breath, sweating and other conditions. It needs timely treatment, otherwise it may lead to cerebral stroke, which is very dangerous.
A study published in the International Journal of epidemiology pointed out that with the increase of the number of heart beats, the risk of diabetes increased by 23% with the increase of 10 beats per minute.
3. Heart failure
Common manifestations of heart failure include tachycardia, arrhythmia, palpitation, etc. if these conditions are not controlled in time, they are very dangerous. For example, an increase in heart rate of 5 times per minute can increase the cardiovascular mortality rate and re hospitalization rate by 15%.
4. Thyroid disease
For example, if hyperthyroidism is not treated in time, it may cause sinus arrhythmia, and serious hyperthyroid heart disease may occur; Or hypothyroidism may increase the incidence rate of heart disease and heart failure.
Reminder: if your heart beats too fast or too slow, especially when you have some uncomfortable symptoms, you should be alert to the "trouble" caused by the disease, and should seek medical attention in time to avoid serious consequences.
3、 A slower heartbeat will lead to a longer life! 4 moves to help your heart slow down
Within the normal heart rate range, if the heart rate is slower, you will live longer. How can you "control" your heart rate?
Regular exercise is an effective measure to reduce heart rate. Some studies have found that moderate intensity exercise for 40 minutes every day for 6 consecutive weeks can effectively reduce the heart rate from 68 times / minute to 53 times / minute.
As for sports, there are no restrictions. Jogging, walking, swimming and badminton are all available. You can choose according to your own preferences.
If a person's weight exceeds the standard too much, the heart will bear a heavy burden, resulting in a faster heart rate. Therefore, managing the body is also a key measure to keep the heart rate normal. The most direct and effective way to keep fit is to keep your mouth shut and walk away.
Peace of mind
Try to keep a calm and happy mind, and don't get angry easily, because anger can make the sympathetic nerve highly excited, release a large amount of adrenaline and noradrenaline, and then lead to rapid heartbeat and blood pressure surge. Some people may be "angry" directly.
Eat less "speed up" food
For example, tea, coffee, tobacco, etc. are all "speed-up" foods. Therefore, we should pay attention to controlling the intake and minimize the exposure.
Conclusion: too fast and too slow heartbeat is not good. Sometimes it may be caused by pathological factors. Therefore, do not blindly believe the so-called "slow heartbeat will lead to longer life" popular on the Internet. If the heart rate is abnormal, especially if you feel unwell, you should seek medical attention in time, follow the advice of professional doctors and treat in time.
