What term refers to the highest blood pressure measured in the arteries during heart contractions?

The term that refers to the highest blood pressure measured in the arteries during heart contractions is systolic blood pressure. This measurement occurs when the heart's ventricles contract and pump blood into the arteries, leading to an increase in pressure. Systolic blood pressure is typically represented as the top number in a blood pressure reading, indicating the maximum force exerted against the artery walls during this contraction phase.

To clarify the context of the other terms: diastolic blood pressure, which is related but refers to the pressure in the arteries when the heart rests between beats; moyn blood pressure is not a recognized term in this context; and mean arterial pressure is a calculation that represents the average pressure in a person's arteries during one cardiac cycle. Thus, the focus on the contraction of the heart specifically aligns with the definition of systolic blood pressure.
