title: Computer analysis of left ventricular pressure-volume relationships by echocardiography.
abstract: Programs were developed for the analysis of left ventricular pressure-volume relationships in clinical situations. Regression lines of end-systolic points on the pressure-volume plane were obtained from nine patients. Correlation coefficients between end-systolic pressure and volume were high. The indices calculated may be useful for diagnosis and research of left ventricular function.
