Answer 2

Answer:

The relation is the reciprocity between the heart rate to the cardiac cycle duration.

Explanation:

The duration of one cardiac cycle includes the relaxation of heart followed by the contraction, this is termed medically as systole and diastole.

$1 cardiac cycle = 1 systole + 1 diastole$

Thereby, one cardiac cycle has one systole and one diastole. Altogether this provides total duration of cardiac cycle and is in inverse proportional ratio to the heart rate.

For instance, we know the average heart rate of a normal human adult is 72 beats per minute, then the duration of cardiac cycle is $1 / 72 beats per min = 0.0139 minutes per beat = 0.8 second per beat$
