Method of reconstructing a surface electrocardiogram from an intracardiac electrogram

摘要

The method involves acquiring intracardiac electrogram signals on intravascular or intracardiac derivations, defined from cavitary electrodes e.g. distal or proximal right ventricle electrodes, and calculating a corresponding intracardiac vector diagram (VGM) by comparison of the intracardiac electrogram signals. A reconstructed surface vectorcardiogram is estimated from the intracardiac vector diagram. Surface vectorcardiogram signals corresponding to the reconstructed surface vectorcardiogram are calculated.
