The study found that the heart rate is related to the length of life, how much is the heart rate better? tell you the answer

"Hey, come here, can someone help you call 120!" Ms. Zhang shouted anxiously.

It turned out that Ms. Zhang and her best friend, Ms. Li, went out for an outing in the park. Who knows, while walking, Ms. Li suddenly fainted in front of her eyes, which frightened Ms. Zhang. With the help of passers-by, Ms. Li was rushed to the hospital.

After an electrocardiogram, the doctor found that Ms. Li's heart rate was very slow, with a heart rate of only 38 beats per minute. The final diagnosis was third-degree atrioventricular block , which caused her heart rate to be too slow, causing fainting.

Later, the doctor learned that Ms. Li had actually discovered her slow heartbeat when she had a physical examination a year ago, and the doctor suggested that she have further examinations.

But Ms. Li was not too relieved, and even thought it was a good thing, because she heard people say that "slow heartbeat leads to longevity" . Even if there is occasional dizziness, she only thinks it is hypoglycemia, and she didn't realize the seriousness of the problem until she fainted this time.

1. The speed of the heartbeat is related to the length of life. How much longer the heartbeat is?

In fact, there has always been controversy about the relationship between the heartbeat speed and the length of life. So how much longer does the heartbeat live?

Under normal circumstances, when an adult is in a quiet state, the heart rate fluctuates between 60 and 100 beats per minute , with an average of 75 beats per minute. If it exceeds 100 beats/min, it is considered to be tachycardia, and if it is less than 60 beats/min, it is considered to be bradycardia.

Is it a fast heartbeat or a slow heartbeat? A study by the "Research Institute of Health" in Taiwan, my country, gave the answer.

The research was carried out by a team led by Professor Wen Qibang, collected and analyzed nearly 2 million health check-up data, and finally found that the heart rate of healthy people is 60-100 beats/min, and as the heart rate increases, the life expectancy will also shorten. ,details as follows:

• Heart rate of 70-80 beats/min, life expectancy shortened by 3 years on average;
• 80~90 times/min, life expectancy is 5 years short;
• The heart rate is 90-100 beats/min, and the life expectancy is 8 years shorter.

In this regard, the explanation given by the doctor is: tachycardia, which can significantly increase the burden on the heart and may further affect life expectancy.

In addition, scientists have also found that animals with slower heartbeats live longer. For example, small mice have a heartbeat frequency of 500 beats per minute, and their average lifespan is about 3 years; cats and dogs have 100 beats per minute, and their lifespan is about ten years. Whales, on the other hand, have a heart rate of 15 to 20 beats per minute and can live up to 80 years old .

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, for healthy adults, within the normal heart rate range, the slower the heart rate, the better; but for patients with hypertension and coronary heart disease, it is most beneficial to control the heart rate within the target value. ill.

That said, both fast and slow heartbeats can be harmful to the body, so maintaining a normal heart rate range is best. If it is within the normal range of 60 to 100 beats per minute, the heartbeat is slower and the life expectancy will be relatively longer .

2. The heartbeat is too fast or too slow, or it is a sign that the disease is coming

Sometimes the heartbeat is too fast or too slow, which may be caused by some diseases. At this time, we must pay attention to distinguish it so as not to delay treatment.

1. Atrial fibrillation

Atrial fibrillation can be caused by a variety of reasons, such as high blood pressure, diabetes, coronary heart disease, smoking and drinking, etc. When this happens, the main manifestation is irregular heartbeat, and patients may experience palpitation, chest tightness, shortness of breath, sweating, etc. , requires timely treatment, otherwise it may lead to stroke, which is very dangerous.

2. Diabetes

A study published in the International Journal of Epidemiology pointed out that with an increase in the number of heart beats, 10 more beats per minute, the risk of diabetes increased by 23%.

3. Heart failure

Common manifestations of heart failure include fast heartbeat, arrhythmia, palpitations, etc. These conditions are very dangerous if not controlled in time. For example, an increase in heart rate of 5 beats per minute can increase cardiovascular mortality and rehospitalization rates by 15%. .

4. Thyroid disease

For example, hyperthyroidism, if not treated in time, may cause sinus arrhythmia, and severe heart disease may occur; or hypothyroidism may increase the incidence of heart disease and heart failure.

Reminder: The heartbeat is too fast or too slow, especially when the body is accompanied by some uncomfortable symptoms, we should be alert to the " causing trouble " of the disease, and seek medical treatment in time to avoid serious consequences.

3. Slower heartbeat and longer life! 4 tricks to help you slow down your heart rate

Within the normal heartbeat range, if the slower the heartbeat, the longer the lifespan, how can you "control" the speed of your heartbeat every day?

• regular exercise

Adhering to regular exercise is an effective measure to lower your heart rate. A study found that 40 minutes of moderate-intensity exercise a day for 6 consecutive weeks can effectively reduce the heart rate from 68 beats/min to 53 beats/min.

As for the sports items, there are no restrictions, such as jogging, brisk walking, swimming, playing badminton, etc. You can choose according to your own preferences.

• maintain weight

If a person's weight exceeds the standard too much, then the burden on its heart will be relatively large, resulting in an increased heart rate, so managing the body is also a key measure to maintain a normal heart rate. And if you want to keep your figure, the most direct and effective way is to keep your mouth shut and open your legs.

• Peace of mind

Try to maintain a calm and pleasant state of mind, and don’t get angry at every turn, because anger can make the sympathetic nerves highly excited , releasing a large amount of adrenaline and norepinephrine, which in turn leads to rapid heartbeat and soaring blood pressure. ".

• Eat less "speed-up" foods

For example , tea, coffee, cigarettes , etc., these are all "speed-up" foods, so usually everyone should pay attention to controlling the intake and minimize exposure.

Summary: It is not good for the heartbeat to be too fast or too slow, and sometimes it may be caused by pathological factors, so don’t blindly believe the so-called “slow heartbeat will lead to longer life” popular on the Internet. If the heartbeat is abnormal, especially if you experience physical discomfort, You should seek medical attention in time, follow the advice of a professional doctor, and get timely treatment.
