Abstract/OtherAbstract:
Differentiation between left- and right-sided inferoseptal accessory pathways by existing ECG algorithms is unsatisfactory. We reviewed the 12-lead ECGs of 113 consecutive patients undergoing successful ablation of a single manifest inferoseptal pathway (40% at the mitral, 60% at the tricuspid annulus). For prediction of a right-sided location, the most useful criteria were a) a negative QRS polarity in all three inferior leads and in V1 (positive predictive value (PPV) 0.90, negative predictive value (NPV) 0.51) and b) a negative QRS polarity in > or =2 inferior leads and in V1 (PPV 0.80, NPV 0.56). A positive QRS polarity in > or =1 inferior lead predicted a left-sided location (PPV 0.54, NPV 0.80). A new algorithm had an accuracy of 76%.
