BACKGROUND
Many criteria have been published to localize accessory pathways from the 12-lead ECG during sinus rhythm. This study analyzed whether the localization of an accessory pathway could be predicted by using the polarity of the QRS complex during sinus rhythm on the surface ECG, instead of the delta wave polarity as used in many reports.
METHODS
The ECGs of 140 patients with an overt and single accessory pathway were evaluated. Eight localizations were taken into account. The precise location was previously known from successful radiofrequency ablation sites.
RESULTS
In 128 patients (92%), the new algorithm allowed an accurate diagnosis of the site of implantation of the accessory pathway.
CONCLUSION
Analysis of the polarity of the QRS complex on five electrocardiographic leads provides an easy, fast and reliable way to localize accessory pathways during sinus rhythm.
背景
已经发表了许多用于在窦性心律时从12导联心电图定位旁路的标准。本研究分析了是否可以通过使用体表心电图在窦性心律时QRS波群的极性来预测旁路的定位，而不是像许多报告中那样使用δ波极性。
方法
对140例明确存在单一旁路的患者的心电图进行评估。考虑了八个定位。精确位置先前已从成功的射频消融部位得知。
结果
在128例患者（92%）中，新算法能够准确诊断旁路的植入部位。
结论
分析五个心电图导联上QRS波群的极性为在窦性心律时定位旁路提供了一种简单、快速且可靠的方法。
