Phases Of Cardiac Cycle Flashcards
Increase in ateial pressure caused by atrial systole
A wave
2 causes of 4th heart sound
Ventricular hypertropy
Filling of ventricle by atrial systole
A wave
4th heart sound
Atrial systole
S1 aka AV valve closure
Isovolumetric ventricular contraction
Wave caused by bulging of tricuspid valve into right atrium
C wave
C wave
Rapid ventricular ejection
Most of the stroke volume is ejected in this phase
Rapid ventricular ejection
Represents repolarization of ventricles
Marks end of ventricular contraction and rapid ventricular ejection
T wave
Represents blood flow into right atrium in its rising phase then to right ventricle in its falling phase
V wave
V wave
Reduced ventricular ejection
Second heart sound what phase
Iso relaxation
“Blip” in aortic pressure that occurs after closure of aortic valve
Dicrotic notch/incisura
Dicrotic notch/incisura what phase
Iso relaxation
Mitral valve opens on what phase
Rapid ventricular filling
S3 what phase
Rapid ventricular filling
