Why the study?

Does atrial septal pacing allow simultaneous pacing of both atria in patients with paroxysmal atrial fibrillation and symptomatic bradyarrhythmias?

Population

4 male patients (73 +/- 3 years) with paroxysmal atrial fibrillation and symptomatic bradyarrhythmias

Comparison

Atrial septal pacing using a standard active… vs Normal sinus rhythm and AAT pacing

Implication

Supports simultaneous biatrial activation via septal pacing in this case; leaves open whether it improves outcomes in paroxysmal AF.

Structured PICO

Does atrial septal pacing allow simultaneous pacing of both atria in patients with paroxysmal atrial fibrillation and symptomatic bradyarrhythmias?

P
Population
4 male patients (73 +/- 3 years) with paroxysmal atrial fibrillation and symptomatic bradyarrhythmias
I
Intervention
Atrial septal pacing using a standard active fixation screw-in lead attached to the interatrial septum, guided by TEE and fluoroscopy
C
Comparator
Normal sinus rhythm and AAT pacing
O
Outcome
Conduction time to the high right atrium, distal coronary sinus, and atrial septumsurrogate

Atrial septal pacing using a standard active fixation lead allows simultaneous pacing of both atria, enabling accurate timing of the left-sided AV delay.
