Is the blood flow in the left ventricle during the isovolumic relaxation period a useful parameter of left ventricular systolic and early diastolic performance?

Left ventricular (LV) early diastolic performance is determined by LV behavior in the late systole to early diastole and may relate to the physical potential of patients. Isovolumic relaxation flow (IRF) velocity was obtained by continuous Doppler echocardiography in the left ventricle from the apex in 26 patients with atypical chest pain and 63 patients… CONTINUE READING
