Does a slower heartbeat affect the heart? Is the slower the heart beating, the healthier?

If a person's heart beats less than 60 times per minute, it is "slow heartbeat", also known as "bradycardia". Normal people or athletes may appear, especially athletes, because regular exercise increases the contraction force of the heart, and the output of blood per beat increases, which is enough for the needs of various organs of the body, so the heartbeat of 50-60 times per minute is enough. However, if the heartbeat is only 30-40 beats per minute, it may be abnormal, and the cause should be investigated.

There are three common causes of slow heartbeat: The first is vagus nerve hyperfunction, which has a nerve center in the medulla of the brain that regulates cardiovascular activity. This center can have the function of suppressing the heartbeat or speeding up the heartbeat.

The vagus nerve is the nerve fiber that is emitted by this center, which is used to innervate the heartbeat and other functions. When the vagus nerve is excited, its terminals can release a substance called "acetylcholine" that acts as a depressant to the heart, slowing the heartbeat. The heart rate caused by "hyperactivity" is mostly regular, although the heartbeat is slow, it is rarely less than 30-40 beats per minute, and normal people, including the elderly, can appear.

The second type of slow heartbeat is called "sick sinus syndrome", or "sick sinus" for short. This is a pathological cardiac manifestation whose pathological changes occur mainly at the pacemaker of the heartbeat ——— the sinus node. The common ** is coronary heart disease, cardiomyopathy and degenerative diseases of the cardiac conduction system in the elderly.

Patients with "sick sinus" have a very slow heartbeat, sometimes only 30-40 beats per minute. The third is the slow heartbeat caused by severe atrioventricular block, that is, the impulse wave sent by the original pacemaker sinus node cannot be transmitted to the atrioventricular node and is blocked, at this time the ventricle has to compensate for its own impulses, so the heartbeat is very slow, once complete atrioventricular block occurs, when the heartbeat is less than 20 times per minute, dizziness, and even fainting and convulsions can occur due to the obvious decline in cardiac blood output that directly affects the cerebral blood supply, which is a serious attack of Ass syndrome. Most of the causes of severe conduction block are organic lesions of the heart itself, such as coronary heart disease, myocardial lesions, or advanced severe changes in some heart diseases.

In short, when the heart beats slowly, it should be considered mainly from the main causes such as "hyperactivity", "sinus disease" and severe conduction block, and it can also be found through a detailed medical history and electrocardiogram examination to find the cause of slow heartbeat, so that it can be targeted.

Does fast or slow heart beat affect health? Is it right that the slower the heartbeat, the longer you live? The doctor told you.

The beating of the human heart, strictly speaking, in the state of sleep at night, it takes about 60 to 68 times per minute to maintain the blood supply and oxygen supply of the body and various organs, and the heartbeat of half an hour of rest during the day should be 75 to 85 times per minute to meet the blood supply of the body organs, which is a realistic common sense, not the best 60 times per minute as said in some books, it is the athlete's heartbeat, which is unrealistic, and it is nonsense to take it for granted. If you sleep 60 times per minute during the day and less than 50 times per minute when you sleep at night, your body organs will be ischemic and hypoxic at night, and in the long run, it will cause many chronic diseases, stomach diseases, kidney diseases, bone hyperplasia, etc.

A person's heart beats less than 60 beats per minute during the day is considered a mild state of heart failure, and the lower it is, the more severe the heart failure becomes. It is true that exercise can increase the heart rate, but it is impossible for people to sleep at night, so the slower the heart rate, not only is it not a healthy phenomenon, but also a phenomenon of heart failure.

The statement that the slower the heart, the healthier it is, is not true, there are no absolutes, and some people with heart disease will also have a heart rate within the normal range.
