“…In dipolar electrocardiotopography (DECARTO), orthogonal ECG signals are transformed by means of a simple mathematical model to represent the equivalent generator of the cardiac electric field äs a uniform double layer with time varying size and location on a spherical surface approximating the ventricular wall, called the image sphere ( Figure I) [1]. Ventricular activation is represented by time series of maps of activated points on the image surface.…”

Theoretical grounds of integral vectors of ventricular depolarization and repolarization and their sum, i.e., the spatial ventricular gradient, have been studied. A systematic description and biophysical interpretation of these parameters are presented based on the distribution of cardiomyocyte action potential parameters in the inhomogeneous bidomain model of the myocardium. Recent medical studies have shown high efficiency and predictive value of the ventricular gradient, its constituents and related parameters, such as the angle between the con-stituents, the acceleration of repolarization, etc. Simple examples for a myocardial strip clarify the relationship between the action potential parameters and the resulting ventricular gradient. An explanation with graphic illustration is given for the very informative decartogram of repolarization acceleration. The results obtained here are useful in the modeling of vectorcardiograms for various pathological conditions of the heart ventricles and for various characteristics of the cardiomyocyte action potential, which determine its shape.

“…In our previous works [1,2,3] we presented a method for the topographic presentation of orthogonal electrocardiograms of ventricular depolarization: the dipolar electrocardiotopography (DECARTO), which provides planar and 3D graphical presentations of ECG comparable with other image techniques [4]. In relation to electrocardiograph)' they are used mainly as reference methods for comparative studies to contribute to the solution of the inverse problem.…”
