Introduction
In echocardiography, EDV usually refers to end-diastolic volume, and ESV refers to end-systolic volume. EDV and ESV are two parameters used in echocardiography to assess left ventricular function, commonly utilized for evaluating cardiac function and hemodynamics. Both EDV and ESV have corresponding reference value ranges. If you experience any discomfort, it is recommended to seek medical attention promptly.
Cardiac color Doppler ultrasound EDV usually refers to end-diastolic volume, while ESV refers to end-systolic volume. The specific analysis is as follows:
EDV and ESV in cardiac color Doppler ultrasound are two parameters used to assess left ventricular function, commonly employed to evaluate cardiac function and hemodynamics. Among them, EDV is an indicator of cardiac systolic function measured during echocardiography, namely the end-diastolic volume, with a normal range of approximately 108±24 mL. An increase in this value indicates impaired cardiac and systolic function. ESV represents end-systolic volume, with a normal value of 45±16 mL; an elevated ESV suggests possible reduction in ventricular contractility.
In addition, left ventricular functional assessment also includes measurements such as left ventricular end-diastolic diameter (LVD), left ventricular end-systolic diameter (LVS), ejection fraction (EF), fractional shortening (FS), and left ventricular ejection fraction (LVEF), which together allow for a comprehensive evaluation of left heart function. Both EDV and ESV in cardiac ultrasound have corresponding reference ranges. If any symptoms or discomfort occur, it is recommended to seek timely medical attention to avoid delaying diagnosis and treatment.
