Diastolic Blood Pressure is the pressure in the arteries when the heart is at rest between beats. It is one of the two measurements used to determine blood pressure, the other being systolic blood pressure, which measures the pressure during heartbeats. Diastolic pressure is important because it indicates how well the heart and blood vessels are functioning when the heart is not actively pumping blood. A normal diastolic blood pressure reading typically ranges from 60 to 80 mmHg. High diastolic pressure can indicate potential health issues, such as hypertension, which may increase the risk of heart disease and stroke. Regular monitoring can help maintain cardiovascular health.
