    Abstract:
    Body surface mapping (BSM) has now become a feasible clinical technique, providing useful information applicable to the diagnosis of cardiac arrhythmias and their treatment by surgical and endocardial catheter ablation. In WPW patients, validation of preexcitation patterns has been obtained by computer simulation and by direct epicardial mapping at surgery. BSM pacemapping has subsequently been developed to be used during radiofrequency catheter ablation. This method has been evaluated prospectively and its predictive accuracy assessed. The recognition of two distinct BSM patterns in idiopathic ventricular tachycardia, has led to the application of successful pacemapping for radiofrequency catheter ablation. The use of a realistic tri-dimensional heart-torso computer model has shown that specific sites of endocardial stimulation are related to distinct thoracic map patterns.
