Accuracy of the new electrocardiogram algorithm in predicting localization of accessory pathways in patients with typical Wolff-Parkinson-White syndrome

Abstract

Objective: This study was to test the accuracy of the newly built electrocardiogram algorithm prospectively by us for the localizing accessory pathways (APs) in typcal Wolff-Parkinson-White (WPW) syndrome. Subject and methods:A new algorithm is proposed for localization of AP by 12 lead electrocardiograms (ECG) before radiofrequeny catheter ablation (RCFA) in 109 patients were compared with AP location confirmed by successful RCFA. Results:The new electrocardiogram algorithm for the localization of AP with high accuracy predicted by simple parameters such as delta wave polarity in lead V1, R/S ratio in V1, the QRS complex transition, delta wave polarity and QRS complex polarity in at least 2/3 inferior leads (DII, DIII, aVF) and QRS complex morphology was Qrs (Qrs, qRs, qrS) in at least 1/3 inferior leads with high sensitivity and high specificity from 75% to 100%. Conclusion:The new ECG algorithms were high accuracy in predicting AP before intervention.
