Original abstract
Predicting the site of accessory pathway in Wolff-Parkinson-White syndrome using body surface mapping is an established examination. For this purpose, many methods have been reported, such as, isopotential maps of QRS wave and ST-T wave, subtraction map of QRS isopotential map, isointegral maps of QRS and QRST waves, and departure map of QRST isointegral map, moving dipole and single value decomposition. The method of determining by the location of the minimum in early QRS isopotential map is most widely used. It should be noted, however, that the prediction is often difficult in posteroseptal accessory pathway and the cases with relatively narrow QRS wave.
