Systolic pressure refers to the maximum pressure exerted in the arteries during the contraction of the heart's ventricles. During the phase of isovolumetric contraction, the ventricles are contracting with no change in volume, as the atrioventricular and semilunar valves remain closed. The pressure in the ventricles rises until it exceeds the pressure in the aorta and pulmonary artery, at which point the semilunar valves open, allowing blood to be ejected into the systemic and pulmonary circulation.

This peak pressure is critical for ensuring effective blood flow and is a key parameter in various cardiovascular assessments. Understanding systolic pressure is essential for evaluating cardiac function, as it provides insight into the strength of the heart's contractions and the workload placed on the heart.
