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.
