Normally, the heart's electrical system triggers the resting heart to beat in this precise sequence 60 to 100 times each minute. This is referred to as normal sinus rhythm. With exercise, the heart rate will increase to above 100 times per minute. A person's peak heart rate can be calculated by subtracting their age from 220.
