Follow-up
Patients were followed every 3 months thereafter. Implantable cardioverter defibrillators were evaluated at each visit, and arrhythmia logs were retrieved. The primary endpoint was a recurrent VT. In addition, we evaluated VT recurrence rate after VT ablation among the total procedures divided into four groups: 1) a target VT was not inducible at the end of the procedure, 2) a target VT was still inducible at the end of the procedure, 3) PES was not implemented because of non-inducibility before RF delivery, 4) PES was not implemented because of other causes.
