Simulation of cardiac activation patterns for checking suggestions about the suitability of multi-lead ECG electrode arrays

Abstract

In this study results gained for different electrode array schemes are compared which are used to image the activation time of the heart in a noninvasive way. The tested arrays have been selected based on sensitivity and effort-gain analysis. A cellular automaton was used for generating 6 different patterns resembling a sinus rhythm overlaid by an accessory pathway. The BSP was computed using a finite element approach. For generating the AT maps a boundary element model was used. It was found that methods for noninvasive imaging of the cardiac electrophysiology can profit from the increased details and features contained in the BSP maps recorded by a 1.25 lead array. © Springer-Verlag Berlin Heidelberg 2006.
