Methods
This retrospective study received approval from the local institutional Ethics Committee, and all participants provided written informed consent. We included all patients who underwent CA for PVCs or non-sustained VT consecutively from May 2019 to July 2022, barring those who met any of the exclusion criteria, which consisted of: (i) an insignificant number of PVCs or non-inducible VT during the procedure, or (ii) follow-up duration of less than 3 months or lost to follow-up. The patients were segregated into two cohorts: the control group who did not utilize ICE, and the ICE group wherein ICE was employed.
