WebNov 1, 2004 · The duration of diastole can be defined in terms of mechanical events. Mechanical diastolic duration (MDD) is comprised by the phases of early rapid filling (E wave), diastasis, and late atrial filling (A wave). The effect of heart rate (HR) on diastolic duration is predictable from kinematic modeling and known cellular physiology. To … A typical heart rate is 75 beats per minute (bpm), which means that the cardiac cycle that produces one heartbeat, lasts for less than one second. The cycle requires 0.3 sec in ventricular systole (contraction)—pumping blood to all body systems from the two ventricles; and 0.5 sec in diastole (dilation), re-filling the four chambers of the heart, for a total of 0.8 sec to complete the cycle.

Examples: aortic and pulmonary regurgitation. Mid-diastolic murmurs (rumble) are due to increased flow (relative stenosis) through the mitral (VSD) or the tricuspid valves (ASD).; Late diastolic murmurs are due to pathological narrowing of the AV valves. Example: rheumatic mitral stenosis. …
