Summary
Investigate the value of unipolar and bipolar electrograms (EGM) for predicting the successful ablation site for idiopathic outflow tract ventricular arrhythmia (OTVA).
Detailed description
The proposed study aims to evaluate the predictive value of using reversed polarity in adjacent bipolar EGMs (bi-RP method) and unipolar EGM with QS morphology (uni-QS method) for identifying successful ablation site, and evaluate the feasibility of enhancing uni-QS method's performance by using its morphology characteristics such as descending slope and symmetry.
