| Zusammenfassung | Recently, several studies have been performed where the functional localization of accessory pathway (AP) in Wolff-Parkinson-White (WPW) syndrome patients, obtained by non-invasive magnetocardiographic (MCG) mapping, were compared with results of invasive electrophysiological study (EPS). Main restrictions of comparing spatial differences in these studies are some methodological incompatibilities between MCG and EPS. Some papers an report alternative approach where the MCG mapping data is used to classify different types of WPW cases either from magnetic field distribution or from propagation of the calculated equivalent current source, superimposed on the magnetic resonance image (MRI). In this study we have introduced cluster analysis of AP direction of propagation to classify different types of WPW patients. We have studied 22 WPW syndrome patients. All patients underwent non-invasive MCG mapping and the invasive EPS before catheter ablation of AP was performed. Spatial coordinates of a moving equivalent current dipole source within different volume conductor models (a half space and a realistic torso model) were calculated from the MCG data in the localization procedure. The current dipole direction of propagation within the AP has been used in clustering procedure. |
