An Analysis of the Time of Occurrence of Mechanical Events in the Heart in Some Heart Diseases with the Ultrasonic Doppler Method

　The ultrasonic Doppler method can be ap-plied in detecting the movement of the heart, especially the movement of the valve without any surgical procedure. With this technique, an analysis of timing of mechanical events of the heart was performed in some heart disease.This method allowed one to pursue the phase in diastole so promisingly unlike other classical methods.

　Discussions are made of the results of the analysis.
