Abstract :

Objective: Th is study was to assessment the accuracy of the new electrocardiogram algorithm in predicting localization of accessory pathway in patients with typical Wolff -Parkinson-White syndrome to compare with accessory pathway location identifi ed by successful RF. Subject & Method: A new algorithm is proposed for localization of accessory pathways by 12 lead electrocardiograms before RF catheter ablation in typical Wolff -Parkinson-White syndrome from 109 patients with Wolff -Parkinson-White syndrome; were compared with accessory pathways location identifi ed by successful radiofrequency catheter ablation. Results: Th e new electrocardiogram algorithm for the localization of accessory pathways with high accuracy predicted by using simple parameters such as polarity delta wave in V1, R/S ratio in V1, the transition of the QRS complex, polarity delta wave/ polarity QRS complex in at least 2/3 inferior leads and morphology QRS was ├ó┬?┬?QRS pattern├ó┬?┬Ł in inferior leads with sensitivity and specifi city from 75% to 100%. Conclusion: Th e surface electrocardiogram parameters of new algorithm in typical Wolff -Parkinson-White syndrome closely related to accessory pathways localization with high sensitivity and specifi city. Th erefore, can be used to a new electrocardiogram algorithm in predicted the location accessory pathways with high accuracy predicted.
