Effectiveness of first versus successive antitachycardia pacing attempts: predictors and clinical consequences

ConclusionsThe effectiveness of ATP is mainly due to ATP-1. The regularization of RR intervals after ineffective ATP-1 underlies the lower efficacy of successive attempts. Shorter PPI-TCLd is associated with higher effectiveness of ATP-2 and ATP-3. Since a duration of QRS ≥ 120 ms predicts a longer PPI-TCLd, patients with wide QRS complexes have less effective ATP-2 and APT-3.
