Question

Quizplus · Accepted Answer

One cardiac cycle consists of one period of diastole, and one period of systole. During diastole, the heart relaxes allowing the chambers to fill with blood. During systole, a large portion of that blood is pumped out of the ventricle. During periods of rest, diastole is usually longer than systole to allow more time for filling.
Before any contraction or systolic phase can occur, there must be an electrical signal coming from the SA node. However, this is not referred to as diastole.
