diastole

Chamber expansion phase

Diastole is the phase of the heartbeat when the heart muscle relaxes and the chambers fill with blood, alternating with systole (contraction).

Blood pressure readings give systolic over diastolic: Her blood pressure was 120 over 80.

The term extends to any rhythmic expansion or dilation.
