Abstract

We have developed a model-based imaging approach to inversely estimate the site of origin of reentrant arrhythmia from body surface potential maps (BSPM), with the aid of an ion-channel-level cardiac model. The reentry was successfully simulated and maintained in the cardiac model, and the simulated ECG waveforms over the body surface corresponding to a maintained reentry have evident characteristics of ventricular tachycardia. The present simulation results show that the present inverse imaging approach achieved an average localization error of about 1.5 mm when 5% Gaussian white noise was added to the BSPMs. This pilot simulation study suggests the feasibility of the model-based imaging approach in localizing the site of origin of reentrant arrhythmias from noninvasive BSPMs.
