During exercise an increase in heart rate corresponds to a shortening of the cardiac cycle (RR interval decreases). Most of this shortening occurs in the TP interval.The QT i â¦ nterval also shortens, but only slightly. then the interval shortens as the heart rate increases.ost of this shortening occurs in the TP interval.
