Key result
Antitachycardia pacing terminated fast ventricular arrhythmias (≥188 bpm) in 3 of 4 episodes, and prolonging detection intervals significantly reduced unnecessary ICD shocks.

Does optimized ICD programming with prolonged detection intervals and antitachycardia pacing reduce unnecessary shocks in patients with ICDs?
Population
Patients with implantable cardioverter/defibrillators (ICDs) for primary or secondary prevention
Comparison
Optimized ICD programming vs Standard or historical ICD programming

May reduce unnecessary ICD shocks; leaves open confirmation in prospective randomized trials.
Does optimized ICD programming with prolonged detection intervals and antitachycardia pacing reduce unnecessary shocks in patients with ICDs?
Optimizing ICD programming with prolonged detection intervals and antitachycardia pacing effectively reduces inappropriate shocks and associated morbidity.
Joerg O. Schwab (2010) conducted a review in Implantable cardioverter/defibrillators for primary prevention. Optimized ICD programming (prolonged detection intervals and antitachycardia pacing) vs. Standard programming was evaluated on ICD shocks and inappropriate therapy. Antitachycardia pacing terminated fast ventricular arrhythmias (≥188 bpm) in 3 of 4 episodes, and prolonging detection intervals significantly reduced unnecessary ICD shocks.
