Your heart's electrical system should maintain: 1  A steady heart rate of 60 to 100 beats per minute at rest. 2  The heart's electrical system also increases this rate to meet your body's needs during physical activity and lowers it during sleep.
When resting, the number of beats per minute slows down. The Karvonen calculation, devised by a Scandinavian physiologist, takes this into consideration by introducing a number called the heart rate reserve into the equation â the difference between your maximal heart rate and your resting heart rate.
