Case Summary:
Capturing intrinsic interatrial conduction with Bachmann bundle (BB) pacing is known as a more physiological atrial pacing strategy than conventional right atrial appendage pacing. We present a 74-year-old man with sinus node dysfunction and paroxysmal atrial fibrillation who underwent dual-chamber pacemaker implantation, incorporating BB and left bundle branch ventricular pacing. Interatrial and atrioventricular synchrony was achieved with a shorter P-wave duration and normalization of the PR interval.
Take-Home Message:
BB pacing may restore physiologic atrial activation by engaging the preferential interatrial conduction pathway and may be beneficial in patients with sinus node dysfunction and atrial arrhythmias.

The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and empty blood into the...
