WebDiastole is defined as the period between aortic valve closure and mitral valve closure (diastole is considered to start with the onset of relaxation of ventricular muscle contraction just proceeding the closure of the aortic valve), which consists of four phases: isovolumic relaxation, rapid filling, diastasis, and atrial systolic phases. WebThere are two basic phases of the cardiac: diastole (relaxation and filling) and systole (contraction and ejection). Diastole represents the period when the ventricles are relaxed (not contracting). Throughout most of …
