Abstract

When the catheter is placed over the origin of the tachycardia, the baseline electrocardiogram and pacing from the catheter are identical. To assist in catheter placement within the heart, a model of the ventricles was constructed to produce electrocardiogram (ECG) signals from different muscle regions. Using the original signal as a template, the model is searched to locate the area with the closest correlation to the baseline, which is then reported to the physician. The computer model, combined with a rule base, can assist in localizing the origin of ventricular tachycardia and decreases the invasive time and risk of mapping procedures
