Abstract :
The ECG inverse problem involves the estimation of cardiac electrical activity such as epicardial potentials from measured precordial potential distribution. In this study, the authors investigate the accuracy and stability of the ECG inverse solution from the viewpoint of the minimum description length principle (MDL). To be specific, the boundary element method is applied to simulate the ECG potential inside a numerically-modeled human thorax and the optimal number of inverse solution components are determined by the MDL principle
