[Application of electrocardiac-gating in echocardiogram analysis].
To study the application of the gating technic in 2D imaging of echocardiogram, thirty normal men and twenty-five patients suspected of having heart diseases were recruited. The electrocardiac R-gating was adopted for collecting phasic images combing with interactive mode of man to computer, recognizing and calculating by computer while delineating the form and structure of heart with the use of mouse to detect the quantitative parameters of cardiac function and left ventricular volume curve. Its application can provide the information of some quantitative parameters for diagnosing the localization of early coronary heart disease and myocardial ischemia.
