"WebTiming intervals are distinct periods that occur during the cardiac cycle and between subsequent cardiac cycles. Pacemaker timing intervals can be compared to the alarms of a clock. At the appropriate ‘time’, the pacemaker delivers a pacing pulse to either the atrium or ventricle, much the same way an alarm rings in a clock at a set time. " - Pacemaker timing intervals
