EGM Analysis in Idiopathic Outflow Tract Ventricular Arrhythmia
Completed
- Conditions
- Ventricular Outflow Tract Tachycardia
- Registration Number
- NCT02722577
- Lead Sponsor
- Abbott Medical Devices
- Brief 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.
