Key result
ATP terminates ~92% of sustained VT episodes, with no single pacing mode proving superior.
Why the study?
The most effective antitachycardia pacing (ATP) mode in patients with third generation cardioverter defibrillators remains uncertain.
Does a specific antitachycardia pacing (ATP) mode improve termination of ventricular tachycardia in patients with cardioverter defibrillators compared to other modes?
Population
65 patients prior to and after third generation cardioverter defibrillator implantation
Comparison
Three different ATP modes with varying coupling intervals and scanning protocols
Design
Randomized prospective testing of ATP modes
Follow-up
Mean 12 months

ATP success similar across modes in this series; leaves open optimal burst parameters for modern ICD programming.

Does a specific antitachycardia pacing (ATP) mode improve termination of ventricular tachycardia in patients with cardioverter defibrillators compared to other modes?
Antitachycardia pacing is highly effective for terminating sustained ventricular tachycardia in ICD patients, though specific programming modes did not show significant differences in efficacy.
Trappe et al. (1994) conducted an RCT in Sustained ventricular tachycardia in patients with cardioverter defibrillators (n=65). Antitachycardia pacing (ATP) modes A, B, and C vs. Each other (Modes A, B, and C) was evaluated on Termination of ventricular tachycardia episodes. Antitachycardia pacing was highly effective in terminating sustained ventricular tachycardia episodes (92% success during follow-up), with no single pacing mode proving superior to the others.
