What is Joint diastole?
During joint diastole both the auricles and ventricles undergo relaxation hence also called complete cardiac. During diastole backflow of the blood from the aorta into the ventricles is prevented by the closing of semilunar Valves. During this phase, auricles get filled with respective blood and the new cardiac cycle begins. The joint diastole lasts for about 0.4 seconds.
