Objective To evaluate the accuracy of the new and old electrocardiographic algorithms for differentiating the origins of outflow tract ventricular arrhythmias. Methods The clinical data of 202 patients treated between 2010 and 2013 were retrospectively reviewed for the investigations of the four algorithms including the transitional zone index, the V2 transition ratio, V2 R-wave duration and R/S-wave amplitude indices and the Sv2/Rv3 index. Results Regardless of rotation, the V2 transition ratio had the highest sensitivity (93.5%), while the Sv2/Rv3 index had the highest specificity (93.8). The maximal area under the ROC curve of four was more than 0.8, while the transitional zone index had the minimal area (0.804) with statistical significance (P < 0.001). In the patients with precordial transition, the V2 transition ratio had the highest sensitivity (93.9%), while the Sv2/Rv3 index had the highest specificity (94.7%). The maximal area under the ROC curve of four was more than 0.8 with no statistical significance (P>0.05). Conclusion Regardless of rotation, the Sv2/Rv3 index has the highest specificity and equal diagnostic value, with equal diagnostic value of the V2 transition ratio and V2 R-wave duration and R/S-wave amplitude indices. Compared with other algorithms, the Sv2/Rv3 index is simple and can be a complement as well for the direction of ablation therapy.
