EGM Analysis in Idiopathic Outflow Tract Ventricular Arrhythmia

July 26, 2019 updated by: Abbott Medical Devices

Usefulness of Unipolar and Bipolar Electrograms in Predicting Successful Ablation Site During Idiopathic Outflow Tract Ventricular Arrhythmia Ablation

Investigate the value of unipolar and bipolar electrograms (EGM) for predicting the successful ablation site for idiopathic outflow tract ventricular arrhythmia (OTVA).

Study Overview

Status

Completed

Intervention / Treatment

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.
