Abstract

We have developed a new efficient optimization algorithm that uses the single equivalent moving dipole (SEMD) model to identify the electrical sources in the heart from body surface electrocardiographic (ECG) signals. In this paper we explored the ability of this algorithm to resolve the relative distance between epicardial pacing sites in an experimental animal model
