Simulation of ventricular ectopic beats with a computer heart model

The simulation of ventricular ectopic beats with a three-dimensional computer heart model incorporating anisotropic propagation is discussed here. The simulated body surface potential maps corresponding to different ectopic sites are in good agreement with clinically described results. The long-term goal is to catalogue surface maps and their corresponding ectopic sites so as to help identify sites of origin of ventricular tachycardia.
