  • Look Inside

The Wolff-Parkinson-White syndrome was mi-micked by stimulating nine different pre-excitation sites in the isolated beating heart of adult mongrel dog which was left in situ (IN SITU isolated beat-ing heart model). The objective was to determine specific body surface isopotential map pattern in each pre-excitation site. During early QRS (δ wave) pe-riod the site of point minimum as well as the vector of points minimum-maximum was found to be charac-teristic in each pre-excitation site. From this ex-perimental study it was concluded that the pattern of isopotential body surface map (the site of point minimum along with the vector of the axis of points minimum-maximum) could provide an easy way to noninvasively diagnose the site of accessory conduc-ion pathways in patients with Wolff-Parkinson-White syndrome.
