	A complete heartbeat represents	Auscultation
	A recording of heart activity	AV node
	Amount of blood pumped out of the heart per beat	Bundle branches
	Represents ventricular repolarization	Cardiac cycle
	Difference between systolic and diastolic pressure	Cardiac output
	Maximum ventricular pressure at contraction	Diastolic
	Responsible for ventricular contraction	EKG
	Nerve fibers that penetrate into the ventricular muscle	Mean arterial pressure
	Nerve fibers traveling down the interventricular septum	P
	Segment representing the conduction time of the AV node	PQ
	Interval representing the time taken for depolarization tospread from SA Node to ventricular muscle	PR
	Interval representing the time between ventriculardepolarizationand the beginning of repolarization	Pulse
	Stroke volume x heart rate	Pulse pressure
	Segment representing venrtricular repolarization	Purkinje fibers
	The pacemaker of the heart	QRS
	The transmission of blood pressure traveling in the bloodvessels when the heart contracts is expressed as	QT
	Waveform representing atrial contraction	SA node
	Waveform representing total ventricular activity	ST
	Repolarization of the atria is found within which wave	Stoke volume
	Firing of th av node occurs at the apex of which wave	Systolic
