WebDiastolic dysfunction is a problem with diastole, the first part of your heartbeat. Typically, your lower heart chambers relax and fill with blood during diastole. Diastolic dysfunction occurs when your lower heart chambers don’t relax as they should. Over time, the dysfunction can lead to diastolic heart failure. Diastole is the relaxed phase of the cardiac cycle when the chambers of the heart are re-filling with blood. The contrasting phase is systole when the heart chambers are contracting. Atrial diastole is the relaxing of the atria, and ventricular diastole the relaxing of the ventricles. The term originates from the Greek word διαστολή (diastolē), meaning "dilatio…
