EGM Analysis in Idiopathic Outflow Tract Ventricular Arrhythmia
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Investigate the value of unipolar and bipolar electrograms (EGM) for predicting the successful ablation site for idiopathic outflow tract ventricular arrhythmia (OTVA).
Condition or disease
Ventricular Outflow Tract Tachycardia
Procedure: Radio-frequency Ablation
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.
