1

AV valves close
S1

Isovolumic contraction

2

Increase in ventricular pressure, same ventricular volume

Isovolumic contraction

3

Ventricular pressure > aortic pressure
Blood from ventricle to aorta

Rapid ventricular ejection

4

T wave

Reduced ventricular ejection

5

Aortic pressure>ventricular pressure
NO BLOOD FLOW yet

Isovolumic contraction

6

Incisure/ aortic notch

Isovolumic relaxation

9

Preceeded by T wave

Isovolumic relaxation

10

Ventricular pressure > atrial pressure

Isovolumic relaxation

13

Semilunar valves close
S2

Isovolumic relaxation

14

Diastasis

Reduced ventricular filling

15

Decrease in ventricular pressure but same volume

Isovolumic relaxation
