ABSTRACT
The systolic time intervals were measured in 25 normal controls and 23 patients with dilated cardiomyopathy by simultaneous recording of the aortic valve echocardiogram and ECG. These values were compared to corresponding ones obtained from the method using simultaneously recorded phonocardiogram, ECG, and indirect carotid pulse tracings. And we assessed left ventricular function by systolic time intervals in dilated cardiomyopathy. The results were as followings. 1) High degree of correlation(r> or =0.94) was found between the two methods for each intervals, EMS, LVET, PEP, PEP/LVET. 2) In normal controls, PEP/LVET obtained from echocardiographic measurement was 0.31+/-0.02. 3) In the patients with dilated cardiomyopathy, PEP/LVET(0.59+/-0.13) was significantly higher(p<0.001), PEP index was longer(p<0.05), LVET index was shorter(p<0.05) than in normal controls.
