A Study of the Spatial Vectorcardiogram of the Ventricular Gradient
A concept of the ventricular gradient as a quantity which varies with time during the cardiac cycle is presented. Some methods for deriving values of the "mean instantaneous ventricular gradient" and from these the "vector-cardiogram of the gradient" are outlined. Despite obvious shortcomings in these technics, some results of the application of these methods are reported.
