In what range is a person's heart rate healthy and what harm does it have if it is abnormal?

Hello! Heart rate varies with age, sex and other physiological conditions. Normal adults average about 75 times/minute (between 60- 100 times/minute). The newborn's heart rate is very fast, reaching 130 beats/min or more. Among adults, women's heart rate is generally slightly faster than that of men. The same person's heart rate slows down when he is quiet or sleeping, and increases when he is exercising or excited. Under the influence of some drugs or neurohumoral factors, his heart rate will increase. People who often engage in manual labor and physical exercise usually have a slow heart rate. In recent years, a large sample study of healthy people in China found that the normal range of resting heart rate in China is 50-95 beats/min for men and 55-95 beats/min for women. I hope it helps you.

The heart is the most important organ of the human body. Its function is to promote blood flow, provide sufficient blood flow for organs and tissues, supply oxygen and various nutrients, take away the end products of metabolism, and maintain normal metabolism and function of cells.

It is said that the number of heartbeats in a person's life is fixed, about 654.38+0 billion, so people with slow heart rate will live longer. This statement is not accurate. The heart beats rhythmically every minute, and its headquarters is in the sinoatrial node, which is located in the right atrium of the human body. Sinus node will produce heartbeat every time it is excited. Heart rate is the number of heartbeats per minute. Traditionally, the normal heart rate is 60~ 100 beats per minute. In fact, the ideal heart rate should be 50 ~ 70 beats/min. If the heart rate is too high for a long time, the chances of suffering from cardiovascular and cerebrovascular diseases will increase in the future, and the mortality rate will naturally increase. Therefore, patients with coronary heart disease and heart failure should control their heart rate more strictly, and the best resting heart rate is 55-60 beats/min.

Generally speaking, the human heart rate will fluctuate within a certain range according to the needs of daily life. For example, when the human body is running, the heart rate of the human body can reach about 130 times per minute, while the heart rate of a person lying still while sleeping is about 40 times per minute. This is a very normal phenomenon. Furthermore, the normal heart rate of many athletes is kept at about 40 beats per minute, which is physiological sinus bradycardia. And if the heart rate is only slow, there is no organic disease in the human body, just keep exercising. This type of heart rate is slow, indicating that the sinus node and heart reserve function are normal, but it is a sign of a strong heart, so don't worry. Of course, if a person's heart rate is less than 50 times, it is abnormal. For example, the heart rate of most patients with heart block is extremely slow, which easily leads to cardiac arrest and is life-threatening.

The heart rate, which measures a person's health, is only one of the indicators, and it is impossible to judge clearly by looking at this data alone. In short, the slower the heartbeat, the healthier it is. This is not absolute. The heart rate of some heart patients will be within the normal range. Therefore, if the heart has related discomfort symptoms and arrhythmia, you must go to the cardiology department of a regular hospital for treatment.
