Secondly, 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 changes with age, sex and other physiological conditions. The normal value of intrinsic heart rate can be calculated according to the following formula:118.1-(0.57× age).
Third: How many heartbeats do you know? An adult's heartbeat is about seventy or eighty beats per minute, but it is normal between 60- 100. An average person lives 100 years old, so the total number of heartbeats can reach about 4 billion.
Fourthly, the normal heart rate at rest is 60- 100 beats per minute, which will increase rapidly during exercise. The specific increase range is different for everyone, which requires targeted analysis, but as long as there are no uncomfortable symptoms and palpitations, it is normal.
Fifth: The heartbeat of a normal person is 60-80 times, and every minute is normal. Everyone's basal heart rate varies with spirit, diet and metabolism. Electrocardiogram and color Doppler echocardiography were performed when necessary. You can avoid bad living habits.
Sixth: the rhythm of normal heart beating is 60- 100 beats/minute. More than 100 is tachycardia. 120 or more, requiring medication. A fast heart rate is not necessarily a heart problem. Usually, for example, when you are nervous or excited, your heart will beat too fast. As long as there is no difficulty breathing, there is generally no need to deal with it.
