Key result
Pre-excitation of the intra-atrial septum by pacing at the coronary sinus ostium or right ventricle prevented atrial tachyarrhythmia triggered by single (0 vs 34 sec, P<0.05) but not multiple APBs.
Why the study?
Does pre-excitation of the intra-atrial septum by pacing at the coronary sinus ostium or right ventricle prevent atrial tachyarrhythmia triggered by single and multiple atrial premature beats in patients with reproducible induction of atrial tachyarrhythmia?

Septal pre-excitation should not yet change practice; leaves open targeted pacing for single-APB triggers pending controlled trials.

Septal pre-excitation by pacing at the coronary sinus ostium or right ventricle prevents atrial fibrillation triggered by single but not multiple premature beats, suggesting limited benefit over sinus rhythm.
Duytschaever et al. (2005) studied Atrial tachyarrhythmia (n=17). Pre-excitation of the intra-atrial septum by pacing at CSO or RV vs. Pacing at the right atrium (RA) and sinus rhythm (SR) was evaluated on Duration of atrial tachyarrhythmia induced by single atrial premature beats (seconds) (p=< 0.05). Pre-excitation of the intra-atrial septum by pacing at the coronary sinus ostium or right ventricle prevented atrial tachyarrhythmia triggered by single (0 vs 34 sec, P<0.05) but not multiple APBs.
