Some arrest rhythms such as pulseless ventricular tachycardia are accompanied by a rhythm display, but there is no contraction Compensatory pause a long beat that compensates for a shorter beat which contains either an atrial or ventricular premature contraction Supraventricular tachycardia rate of 150-250 bmp, narrow qrs complex Paroxysmal supraventricular tachycardia sudden attacks of rapid heartbeats
