Abstract:
Objective To analyze the effect of dominant accessory atrioventricular pathways (AP) on the end vector of ventricular depolarization. Methods All patients had single AP confirmed by radiofrequency cathteter abalation (RFCA) and were free from organic heart disease (including 102 cases of dominant accessory AP and 38 cases of concealed AP). The AP was divided into posterior septal(P3) ,mediate septal (MS) ,anterior septal (AS), left posterior free wall (LP), left anterior free wall (LA), right posterior free wall (RP) and right anterior free wall (RA). Results The end 40 ms vector of QRS wave changed in 102 patients with manifested AP and in 4 patients with concealed AP (P < 0. 05). Conclusion The end 40 ms vector of QRS wave of any site manifested AP can change and the changes have the specihty of leads.
