PATHOLOGY

Detailed explanation-1: -The diastole starts with the closing of the aortic valve and terminates with the closing of the tricuspid or mitral valve. This period includes ventricular filling and relaxation. The diastole indicates when blood vessels revert blood to the heart, preparing for the following ventricular contraction.

Detailed explanation-2: -During diastole, your lower heart chambers (ventricles) relax as they fill with blood. Diastolic dysfunction may occur when your ventricles are stiff and don’t relax properly. When this happens, your ventricles don’t fill with blood as they should, and you may experience pressure buildup in your heart.

Detailed explanation-3: -Diastole is when the heart muscle relaxes. When the heart relaxes, the chambers of the heart fill with blood, and a person’s blood pressure decreases.
