During which phase of the cardiac cycle does systolic pressure occur?

Systolic pressure occurs during the phase of the cardiac cycle when the heart is actively pumping blood. This phase corresponds to ventricular contraction, known as systole, when the ventricles contract and eject blood into the arteries. The pressure exerted on the arterial walls during this period is referred to as systolic pressure. This is critical for understanding how blood pressure measurements are taken and what they signify about heart function and blood flow.

The other phases of the cardiac cycle, such as when the heart is filling with blood or relaxing, are associated with diastole, during which diastolic pressure is measured. Understanding the distinctions between these phases is crucial for accurately interpreting cardiovascular function and health.
