• Diastole and systole occur simultaneously.

2. Isovolumetric ventricular contraction  ( Ventricular systole  1st Phase)

3. Rapid and reduced ventricular ejection  (Ventricular systole  2nd Phase)

4. Isovolumetric ventricular relaxation  (Ventricular diastole  - Early)

5. Rapid and Reduced ventricular filling   (Ventricular diastole  - Late)
