3. Cardiac cycle Systole 1. period of tension asynchrony contraction
isometric contraction
(all valves are closed)
2. period of ejection
protosphigmic interval (opening of semilunear valves)
fast ejection
slow ejection

4. Systole of ventricles 1. period of tension phases of asynchrony contraction isometric contraction (all valves are closed)

5. Systole of ventricles period of ejection protosphigmic interval (opening of semilunear valves fast ejection slow ejection

6. Cardiac cycle Diastole
1. Period of relaxation
protodiastolic interval (closing of semilunear valves)
phase of isometric relaxation (opening of AV-valves is end of this phase)
2. Period of filling
phase of rapid filling
phase of slow filling
phase of filling by help of atrium systole

7. Diastole of ventricles Period of relaxation protodiastolic interval (closing of semilunear valves) phase of isometric relaxation (opening of AV-valves is end of this phase)

8. Diastole of ventricles Period of filling phase of rapid filling phase of slow filling

9. Diastole of ventricles Period of filling by help of atrium systole
