Question: 1 / 400

What does diastole refer to in relation to cardiac function?

Contraction of the heart muscle

Relaxation phase of the heart cycle

Diastole refers specifically to the relaxation phase of the heart cycle. During this phase, the heart muscle relaxes after contracting and allows the chambers of the heart to fill with blood. This is crucial for maintaining adequate blood flow throughout the body and ensuring that the heart can effectively pump blood during the subsequent contraction phase, known as systole.

Understanding diastole is essential in cardiac rehabilitation, as it helps professionals assess the overall efficiency of the heart and the effectiveness of the cardiac cycle. The ability of the heart to relax properly can impact cardiac output and overall heart function, making knowledge of this phase vital for monitoring heart health and optimizing rehabilitation strategies.
