The answer is 0.8 seconds. The heart beats 75 times per minute. Ventricular systole is 0.3 seconds and dilation is for 0.5 seconds. And the complete cycle of systole and diastole together constitute 0.8 seconds. This is because a cycle involves pumping the blood to all body systems through 2 ventricles (0.3 seconds) and refilling the 4 chambers of the heart (o.5 seconds).
