The heart is the body's "blood pumping center", and under normal circumstances, it beats rhythmically like a clock. But the beating of the heart is not a constant value, too fast or too slow needs to be paid attention to... Recently, in a variety show, the well-known actor Wu Zun was accused of "having a heavy heart" after checking his pulse on the spot, and he needed to pay attention to his heart health
As for the cause of "heavy heart", the doctor pointed out that it may be related to long-term sleep deprivation
In this regard, Wu Zun said that he noticed that his heart rate was slow at first, and his heart rate was even only 38 when he got up in the morning, and it was usually around 50, and the topic quickly appeared on the hot search
When it comes to slow heartbeat, many people may feel it
Isn't it healthier to have a slow heartbeat? Wu Zun also said that he thought he had been an athlete before, so he agreed that his slow heartbeat was not a bad thing
But in this regard, the doctor said that if the athlete's heart rate is around 50, there is no problem, but 38 is still a little slow, and it is recommended that Wu Zun usually pay more attention to rest
After the topic rushed to the hot search, it sparked a lot of discussion among netizens
01
The heart is pounding, how much is considered normal?
Usually awake and quiet, the heart beats 120~140 times per minute in infants, 90~100 times in toddlers, 80~90 times in school-age children, and 70~80 times in adults.
But heart rate is not static, it is related to mood, diet, illness, exercise, and other factors. Generally speaking, 60~100 times/min in the resting state is within the normal range.
Although it is generally believed that a slower heart rate is conducive to health and longevity, there is a limit to this "slowness", and if it is less than 60 beats per minute, it is considered bradycardia.

Heartbeat that is too fast or too slow is dangerous
If the heart rate is more than 100 beats per minute at rest, it is called tachycardia, and if it is less than 60 beats per minute, it is bradycardia, and both conditions are very dangerous!
The faster the heartbeat, the more dangerous the blood vessels
Because each beat of the heart brings a blood flow pulse and the passive elastic relaxation of the blood vessels, it is a shock to the arteries of the whole body. Under the action of various forces, the more the number of heartbeats, the greater the damage to the arteries, and the more prone to atherosclerosis and vascular endothelial damage.
In addition, heart rate is the common result of the regulation of the human nervous and endocrine systems, and the increase in heart rate may be a manifestation of various pathological processes such as hypersympathetic nervous system and excessive secretion of catecholamine hormones.
These factors are important mechanisms in the formation of diseases such as hypertension, arteriosclerosis, and heart failure.
A study published in the Journal of the American Medical Association published that observations in community populations showed that a 5 beats per minute increase in heart rate was associated with a 13% increased risk of heart failure and a 13% increased risk of death!
The heartbeat is too slow and the pumping is insufficient
Severe slow heartbeat (less than 45 beats/minute) can easily cause blood flow to slow down, blood and oxygen supply to the whole body organs becomes poor, and patients will have adverse reactions such as dizziness, fatigue, chest tightness, shortness of breath, etc., which will be life-threatening in severe cases. Generally speaking, people who are physically active and exercise regularly are more likely to have a slow heart rate.
In addition, it is normal for professional athletes or long-term heavy workers to have a heart rate of less than 60 beats per minute or even reach 40 beats per minute. Whether bradycardia should be treated by a doctor should first look at the symptoms.

A pounding heart can also be a sign of illness
Thyroid disease
Abnormal thyroid function can affect the heart. Because the thyroid hormone secreted by it is a systemic hormone, it has an impact on various organs, especially the heart, which can regulate blood pressure, heart rate, myocardial oxygen consumption and contractility, cardiac function, etc.
Like hypothyroidism, the secretion of thyroid hormone is too low, which will weaken the contractile function of the myocardium, affect the production and conduction of electrical activity in the heart, and then lead to slow heartbeat and conduction block;
Hyperthyroidism, on the other hand, is the overproduction of thyroid hormones, which may increase blood pressure and increase heartbeat.
Atrial fibrillation
Atrial fibrillation is a disturbance of the heartbeat in the atria and is common in older people. Data shows that about 10% of people over the age of 75 develop atrial fibrillation, and about 20% of people over the age of 80 develop atrial fibrillation.
Atrial fibrillation is manifested as fatigue, palpitation, restlessness, etc., and the self-feeling that the heart is beating in no rhythm, and after measurement, it is found that the heart rate exceeds the normal range, reaching more than 100 beats per minute.
In the event of atrial fibrillation, intervention should be made as soon as possible, otherwise the atria do not contract for a long time, which may lead to continuous blood accumulation, the formation of blood clots, and increase the risk of stroke.
Early-hsien
Premature beats, also known as intermittent, are heart rhythm disturbances that beat once earlier and pause longer than normal. Premature beats do not necessarily mean that there is a heart problem, sometimes they may be caused by excessive nervousness, fatigue, or smoking, drinking, coffee, etc. At this time, you can adjust your lifestyle and you can improve. However, a small number may be related to heart diseases such as coronary heart disease, valvular disease, and cardiomyopathy.
Therefore, if premature beats occur, do not take them lightly and it is advisable to go to the hospital for a check-up to find the root cause.
