What is the pressure in the arteries during left ventricle contraction called?

The pressure in the arteries during left ventricle contraction is referred to as systolic pressure. This phase of the cardiac cycle occurs when the heart's left ventricle contracts and pumps blood into the aorta, leading to a peak in arterial pressure. Systolic pressure represents the highest level of pressure within the arteries, which is critical in assessing cardiovascular health.

In this context, systolic pressure is measured in millimeters of mercury (mmHg) and serves as an important indicator of the heart's performance and arterial health. It reflects the force exerted by the blood against the arterial walls during ventricular contraction, providing essential information about the body's circulatory system. Understanding systolic pressure is vital for EMTs as it aids in recognizing signs of potential cardiovascular issues during patient assessments.
