Diastolisesta

Diastolisesta refers to the diastolic phase of the cardiac cycle. This is the period when the heart muscle relaxes after contracting. Specifically, it describes the relaxation of the ventricles, the lower chambers of the heart. During diastole, the heart fills with blood from the atria, which are the upper chambers. This filling phase is crucial for preparing the heart to pump blood effectively to the lungs and the rest of the body during the subsequent systolic phase.

Blood pressure measurements are often expressed using two numbers: systolic and diastolic. The diastolic pressure is the lower number and represents the pressure in the arteries when the heart is at rest between beats. This measurement is important for assessing cardiovascular health. High diastolic pressure can indicate a condition known as diastolic hypertension, which, like systolic hypertension, increases the risk of heart disease and stroke. Conversely, very low diastolic pressure can also be a concern, potentially indicating issues with blood circulation or heart function. Understanding diastole is fundamental to comprehending how the heart functions and how blood pressure is regulated.
