diástole
Diástole refers to the relaxation phase of the heart cycle. During diastole, the heart muscle, specifically the ventricles, relaxes and expands. This relaxation allows the chambers to fill with blood returning from the body and lungs. It is the counterpart to systole, which is the contraction phase of the heart.
The cardiac cycle is divided into two main phases: systole and diastole. Diastole is crucial for effective
There are different stages within diastole, including isovolumetric relaxation, where the ventricles begin to relax, and
In clinical terms, diastolic blood pressure is the lowest blood pressure reading, measured during diastole when
