DIASTOLIC PRESSURE Meaning and
Definition
-
Diastolic pressure refers to the lower number recorded when measuring blood pressure, commonly expressed as millimeters of mercury (mmHg). It represents the pressure exerted on the arterial walls when the heart is at rest, specifically during the diastolic phase of the cardiac cycle.
During diastole, the heart relaxes between beats, allowing the coronary arteries to supply blood and oxygen to the heart muscle itself. At this stage, the ventricles of the heart are filling with blood, preparing for the next contraction. Diastolic pressure indicates the resistance within the arteries, revealing the pressure that remains in the vessels during this relaxation phase.
It is important to note that blood pressure is typically expressed as a ratio, such as 120/80 mmHg, where the diastolic pressure is the second, lower number. Normal diastolic pressure typically ranges from 60 to 80 mmHg. However, persistently high diastolic pressure can be an indicator of hypertension (high blood pressure). On the other hand, excessively low diastolic pressure may suggest an underlying medical condition, such as heart failure or shock. Regular monitoring of blood pressure, including diastolic pressure, is crucial for assessing overall cardiovascular health and detecting any abnormalities or potential risks to a person's well-being.

Etymology of DIASTOLIC PRESSURE
The word "diastolic" is derived from the Greek words "dia", meaning through or between, and "stole", meaning "contraction". The word "pressure" originates from the Latin word "pressura", meaning "to press". Therefore, "diastolic pressure" combines these two elements to refer to the pressure exerted on the blood vessel walls during the relaxation phase of the heart's cardiac cycle, occurring between two contractions (systole).
