The relation between Doppler and digitized M-mode echocardiographic indexes of left ventricular (LV) diastolic function was analyzed. Diastolic variables obtained with these 2 techniques were compared in 19 normal volunteers and in 25 patients with a variety of cardiac diseases. The 2 techniques were in agreement in distinguishing normal from abnormal diastolic function in 20 of the 25 patients (80%) with cardiac disease. Furthermore, a close linear relation with a high correlation coefficient and a small standard error of the estimate was identified between measurements of isovolumic relaxation determined by Doppler and by M-mode echocardiography (r = 0.82, standard error of the estimate = 18 ms). Doppler indexes of diastolic filling such as the slope (descent) and the duration of the early diastolic flow-velocity peak did not show a close correlation with the peak rate and the time to peak rate of increase in LV internal dimension determined by digitized echocardiography. Thus, Doppler and digitized echocardiography were consistent in distinguishing normal from abnormal diastolic function in most of the study patients, although specific variables of LV ventricular filling determined by the 2 techniques were not closely related. In addition, Doppler and M-mode echocardiographic measurements of isovolumic relaxation showed an excellent correlation.
