Objective: Th is study was designed characteristics of 12 lead electrocardiogram to compare the position of accessory pathway in the typical Wolff -Parkinson-White syndrome, can build a new electrocardiogram algorithm for the localization of accessory pathway. Subject & Method: In 189 patients, typical Wolff -Parkinson-White syndrome have a single anterogradely conducting accessory pathways on 12-lead electrocardiogram parameters were compared with the localization of accessory pathways identifi ed by successful radiofrequency catheter ablation. Result: We found that the 12 lead electrocardiogram parameters in typical Wolff -Parkinson-White syndrome such as polarity delta wave in V1, R/S ratio in V1, the transition of the QRS complex, polarity delta wave/polarity QRS complex and morphology QRS was â??QRS patternâ? in inferior (DII, DIII, AVF) leads in diagnosis for the localization of accessory pathways with height accuracy predicted from 74.5% to 100%. Conclusion: Th e surface electrocardiogram parameters in typical Wolff -Parkinson-White syndrome closely related to accessory pathways localization and can be used as a new electrocardiogram algorithm for the localization of accessory pathways by using simple parameters as above.
