A complete heart beat represents -cardiac cycle
A recording of heart activity - EKG
Amount of blood pumped out of the heart per beat - stroke volume
Represents ventricular repolarization - ST
Difference between systolic and diastolic blood pressure - pulse pressure
Maximum ventricular pressure at contraction - systolic
Responsible for ventricular contraction -AV node
Nerve fibres that penetrate into ventricular muscle- Purkinje fibres
Nerve fibres that travel down in to interventricular septum- bundle branches
Segments representing the conduction time of AV node- PR segment
Interval representing the time taken for depolarization to spread from SA Node to ventricular muscle - PQ
Interval representing the time between ventricular depolarization and beginning of repolarization - PR
Stroke volume * 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 - mean arterial pressure
Waveform representing atrial contraction - P wave
Waveform representing total ventricular activity -QRS
Repolarization of the atria is found within which wave - P
Firing of th av node occurs at the apex of which wave _ PQ
