Usefulness of the over‐the‐wire microelectrodes catheter in treatment of ventricular arrhythmia arising from the left ventricular summit

Abstract

The OTW microelectrodes-guided ablation of OTVA from the vicinity of the LVS was effective. In maximizing the efficacy of ablation, CVS branch mapping is important since the earliest activation was commonly recorded not in the main trunk but within the branch of the CVS.
