Long-term outcome and mode of recurrence following noninducibility during noninvasive programmed stimulation after ventricular tachycardia ablation.

When spontaneous or inducible VTs are eliminated with ablation and no longer inducible during NIPS, these VTs are unlikely to recur during long-term follow-up. More commonly, new VTs occur, which are either associated with areas of scar not present or not targeted during the initial ablation.
