Abstract :
A method for computing the activation sequence at the ventricular surface from body surface potentials, has been adapted to handle measured data. By using measured anatomical data together with a 64-channel ECG (electrocardiogram) recording of the same subject for three subjects, it is shown that the model is able to determine activation sequences on the heart surface which closely resemble similar data obtained through invasive measurement as reported in literature.
