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

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

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

Systole of ventricles 2. period of ejection protosphigmic interval (opening of semilunear valves fast ejection slow ejection

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

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)

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