The heart is one of the most important organs in our body, which determines people's physical and mental state every day. Normal people's heartbeat has a certain amplitude standard. If it exceeds or falls below this standard, symptoms of heart discomfort will appear. For example, if many people feel uncomfortable in their hearts, they are likely to have arrhythmia symptoms such as tachycardia or bradycardia, and the heartbeat amplitude of people of different ages and different physical states is also different.
First of all, according to the difference of people's age and cardiopulmonary function, there are significant individual differences in resting heart rate of normal adults, with an average of about 75 beats/min (between 60- 100 beats/min). Heart rate may vary with age, sex and other physiological conditions. 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. Therefore, the heart rate varies with age, sex and health.
Secondly, the heart rate of healthy adults is 60 ~ 100 beats/min, most of which are 60 ~ 80 beats/min, and women are slightly faster; Children under 3 years old often exceed 100 times/minute; Older people are slow to respond. When the adult's heart rate exceeds 100 beats per minute (generally not more than 160 beats per minute) or the infant exceeds 150 beats per minute, it is called sinus tachycardia. Common in normal people after exercise, excited, excited, smoking, drinking, drinking strong tea. It can also be seen in fever, shock, anemia, hyperthyroidism, heart failure and the application of atropine, adrenaline and ephedrine.
The heartbeat of healthy people is within the normal range most of the time, that is, 60- 100 beats/minute. But it also includes some special situations mentioned above, such as sports and drinking. Because the normal beating of the heart can meet the normal blood supply mechanism of the human body, it is very necessary to keep the heartbeat within the normal range, which determines our health.
