Why the study?
Although second-generation A-ATP reduces AT/AF burden, the clinical characteristics of patients in whom the therapy is effective remain unclear.
What are the predictors of effectiveness for atrial antitachycardia pacing in reducing atrial tachyarrhythmia burden?
Observational (n=12)
No
What are the predictors of effectiveness for atrial antitachycardia pacing in reducing atrial tachyarrhythmia burden?
Absolute Event Rate: 80% vs 14%
p-value: p=<0.02
A history of catheter ablation or Maze surgery, and a prolonged F wave cycle length on 12-lead ECG are useful pre-implantation predictors of atrial antitachycardia pacing efficacy.
