Clinical study of left ventricular diastolic function in patients with heart disease by M-mode color Doppler echocardiography / 中华超声影像学杂志

ABSTRACT

Objective To evaluate the value and accuracy of M-mode color Doppler echocardiography for detecting left ventricular diastolic function in patients with cardiac disease. Methods The rate of left ventricular filling flow propagation (Vp) and the early -diastolic peak velocity of the mitral annulus(E) was measured in normal subjects(n=40)and in patients with cardiac disease (n=40). All the patients had abnormal left ventricular diastolic function confirmed by isotope-angiography test. Results ① The Vp was significantly lowered in patients with cardiac disease than in normal subjects(P
