Heartbeat is a symbol of life and an extremely important physiological activity in the human body. The speed of the heartbeat directly affects the health of the human body. So, what is the relationship between the speed of the heartbeat and the length of life? This article will demystify this relationship for you.
1. Fast heartbeat and longevity.
A fast heartbeat means that the heart contracts and relaxes too many times in a minute. This will lead to an increase in the burden on the heart muscle, which can easily lead to myocardial fatigue, which in turn will lead to a series of cardiovascular diseases. Studies have shown that people with a long-term fast heartbeat have an increased incidence of cardiovascular disease and mortality.
In addition, a fast heartbeat can also lead to an increase in blood pressure. Long-term hypertension can damage vascular endothelial cells, leading to atherosclerosis, which in turn leads to cardiovascular and cerebrovascular diseases. Therefore, for people with a long-term fast heartbeat, controlling heart rate is of great significance for prolonging life.
2. Slow heartbeat and longevity.
Slow heartbeat is when the heart contracts and relaxes too few times in a minute. Although slow heartbeat can reduce the oxygen consumption of the heart muscle to some extent and reduce the burden on the heart, there are also some potential health risks associated with slow heartbeat.
First of all, a slow heartbeat may lead to a lack of blood supply to the brain, causing symptoms such as fainting and dizziness. In severe cases, A-S syndrome may even occur, which is life-threatening. Secondly, slow heartbeat may also cause cardiovascular diseases such as myocardial ischemia and angina.
Therefore, a slow heartbeat is not a good sign. For people with slow heartbeat, they should seek medical examination in time to understand the specific cause and do it under the guidance of a doctor**.
3. Normal heartbeat and lifespan.
A normal heartbeat is when the heart contracts and relaxes within a certain range in one minute. In general, a normal adult's heart rate at rest is between 60 and 100 beats per minute. It is also normal for an athlete or a person with good physique to have a heart rate of slightly less than 60 beats.
Maintaining a normal heartbeat for a long time is important for prolonging life. Studies have shown that people with a heart rate of 70-80 beats have a lower morbidity and mortality from cardiovascular disease than those with a heart rate of 90-100 beats. In addition, a study of 450,000 adults found that those with a heart rate of 70 to 89 beats had a 26% lower mortality rate than those with a heart rate of more than 100 beats.
Therefore, maintaining a normal heartbeat is one of the important ways to prevent cardiovascular disease and prolong life. People can lower their heart rate by improving their lifestyle habits, controlling their weight, reducing stress, etc. In addition, regular check-ups and electrocardiograms (ECGs) are also effective means of early detection of heart problems.
In short, the speed of the heartbeat is closely related to the length of life. Maintaining a normal heartbeat is one of the important ways to prevent cardiovascular disease and prolong life. For people who have a long-term fast or slow heartbeat, they should seek medical examination in time to understand the specific cause and do it under the guidance of a doctor**. At the same time, people should also pay attention to measures such as improving lifestyle habits, controlling weight, and reducing stress to lower the heart rate and maintain a healthy mindset and lifestyle.
