A complete heartbeat represents - Cardiac Cycle
A recording of heart activity - EKG
Amount of blood pumped out of the heart per beat - Cardiac Output
Represents ventricular repolarization - ST
Difference between systolic and diastolic pressure - Pulse pressure
Maximum ventricular pressure at contraction - Systolic
Responsible for ventricular contraction - AV node
Nerve fibers that penetrate into the ventricular muscle - Purkinje fibers
Nerve fibers traveling down the interventricular septum - Bundle branches.
Segment representing the conduction time of the AV node - PR
Interval representing the time taken for depolarization to spread from SA Node to ventricular muscle - PQ
Interval representing the time between ventricular depolarizationand the beginning of repolarization - QT
Stroke volume x heart rate - Cardiac output
Segment representing venrtricular repolarization - ST
The pacemaker of the heart - SA node
The transmission of blood pressure traveling in the blood vessels when the heart contracts is expressed as -Pulse
Waveform representing atrial contraction - P
Wave form representing total ventricular activity - QT
Repolarization of the atria is found within which wave - There is no wave representing repolarization of atria
