2. Cardiac cycle Systole of atrium Діастола передсердь Systole of ventricles Діастола шлуночків

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. Systoleof ventricles1. period of tensionphases of asynchrony contractionisometric contraction (all valves are closed)

5. Systoleof ventricles2. period of ejection protosphigmic interval (opening of semilunear valvesfast 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
