The aim of this study was to develop normal values, including Z-score tables when appropriate, for systolic time (St) and diastolic time (Dt) intervals measured by Doppler … 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.
