"WebRate hysteresis refers to prolongation of the LRI following a sensed event to promote intrinsic rate. Therefore in rate hysteresis, the escape interval is longer than the automatic interval 12 (Fig. 36-9). The longer interval that is allowed in the presence of intrinsic rhythm is termed the hysteresis interval. " - Heart rate hysteresis
