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.
