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.
In a blood pressure recording the top number represents systole, while the bottom number represents diastole.
