How many times a normal heartbeat per minute?

Under normal circumstances, the adult heart rate is between 60-100 beats per minute, which is sinus rhythm.

The heart rate of the human body will be affected by the external environment, temperature changes, diet and emotions. When strenuous exercise, drinking stimulating drinks or emotional excitement, the heart rate will increase, but generally after proper rest and calm, the heart rate will gradually return to normal.

However, if the patient's heart rate is too fast or too slow for a long time, exceeding the normal range, it is abnormal. It is necessary to go to the hospital as soon as possible for blood routine, endocrine measurement, cardiac function and other examinations to clarify the cause.
