The number of times a normal adult’s heart beats before exercise, i.e. at rest, is also known as the heart rate, with a normal range of 60 to 100 beats per minute. In a resting state, the number of heartbeats per minute in a normal adult is also known as the heart rate within the range of 60 to 100 beats per minute, also known as the quiet heart rate. Quiet heart rate varies according to gender, age and other physiological factors. For example, a woman’s heart rate is faster than a man’s under the same conditions, an older person’s quiet heart rate is slower than a young person’s, and an athlete’s heart rate is slower than an average adult’s, all of which are physiological phenomena. In the resting state of the heart rate more than 100 beats / minute, become tachycardia; less than 60 beats / minute is bradycardia, if there is tachycardia or bradycardia discharge physiological factors, it is recommended to go to the hospital to clarify the cause, under the guidance of the doctor to standardize the treatment.
