What is the term for blood pressure measured during heart relaxation?

The term for blood pressure measured during heart relaxation is diastolic pressure. This is the pressure in the arteries when the heart is at rest between beats, allowing the chambers of the heart to fill with blood. During this phase, the heart muscle is relaxed, and the blood pressure is at its lowest point. It is essential for understanding cardiovascular health, as a consistent elevation in diastolic pressure can indicate conditions such as hypertension.

Systolic pressure, on the other hand, refers to the pressure in the arteries during the contraction of the heart muscle when blood is pumped out of the heart. Cardiac output measures the total volume of blood the heart pumps per minute and does not directly relate to the resting state of the heart. Pulmonary pressure measurements pertain to the blood pressure in the pulmonary arteries, which carry blood from the heart to the lungs, and are not relevant when discussing the relaxation phase of heart activity. Understanding these distinctions helps in interpreting blood pressure readings and managing cardiovascular health.
