About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients scheduled to undergo ablation for idiopathic OTVA
  • Have the ability to provide informed consent for study participation.

Exclusion criteria

  • Be currently participating in any other investigational study
  • Be less than 18 years of age
  • Be pregnant
  • Has any other conditions that are not suitable for catheter ablation (including but are not limited to active whole-body infection or sepsis, coagulation or hemorrhage disorder history)

Treatment and study plan

Radio-frequency Ablation

Procedure

A procedure that uses radiofrequency energy to destroy a small area of heart tissue that is causing rapid and irregular heartbeats.

Primary outcomes

  1. Percent of Ablation Targets With Termination of the Clinical Ventricular Arrhythmia After RF Energy Delivery

    Time frame: Intraoperative, an average of 2 hours
