Events of cardiac cycle (along with approximate durations)

Events of cardiac cycle -



1. Atrial systole - 0.1seconds

2. Isovolumetric Contraction - 0.03 seconds

3. Rapid Ventricular Ejection Phase - 0.09 seconds

4. Slow ventricular Ejection Phase - 0.18 seconds

5. Protodiastole + Isovolumetric Relaxation - 0.06 seconds

6. Rapid Passive Ventricular Filling - 0.17 seconds

7. Slow Passive Ventricular Filling - 0.17 seconds

Total - 0.8 seconds



Note -

Atrial Systole - 0.1seconds

Atrial Diastole (includes phases 2-7) - 0.7 seconds



Ventricular systole (includes phases 2-4) - 0.3 seconds

Ventricular diastole (includes phases 1, 5-7) - 0.5 seconds
