End-Diastolic Volume

End-diastolic volume (EDV) is the volume of blood in the ventricle of the heart at the end of diastole, i.e. at the moment of relaxation of the ventricle and opening of the atrioventricular valve. EDV depends on the volume of blood flowing into the ventricle at the beginning of diastole.

End-diastolic volume is one of the important indicators in the diagnosis of heart failure, as it reflects the ability of the heart to fill with blood during the period of relaxation. If EDV is elevated, it may indicate that the heart is not able to pump blood effectively and may be associated with various heart diseases such as heart failure, coronary artery disease, and others.

Normal end-diastolic volume is approximately 100 ml in men and 90 ml in women. However, this indicator may vary depending on age, gender, physical activity and other factors. For example, in older people the EDV may be slightly higher than in young people, and in athletes it may be lower than in people without physical activity.

End-diastolic volume (EDV) is one of the important indicators of cardiac activity, which allows you to estimate the amount of blood in the left ventricle at the end of systole (cardiac cycle). EDV is an important indicator not only for diagnosing heart pathologies, but also for assessing the effectiveness of treatment of these pathologies.

EDV begins with the filling of the chambers of the ventricles of the heart with blood. This occurs when the heart valve opens wide, allowing blood to flow freely into the ventricles. After the end of this period, the ventricular chamber is called end-diastatic or simply diastadic.

Thus, the volume of the ventricular chambers at the end of systole and end of diastole is calculated using bifunctional (two-dimensional) echocardiography and reflects the final volume of the left ventricular core. A change in volume may be a consequence of disturbances in hemodynamics or blood flow in the vessels. These data allow you to visualize various types of heart failure, heart rhythm disturbances and other abnormalities.

The importance of EDV is determined by the fact that an increase in this indicator may indicate the presence of congestive heart failure. If a patient with a high EDV value does not have signs of chronic heart failure, he may be suffering from arrhythmia. In any case, the examination should be carried out by a qualified cardiologist to accurately determine the cause of deviations in this parameter.
