Implication

CS recordings may not equate to LA activity during arrhythmias or pacing; hypothesis-generating and should not yet change practice.

Structured PICO

Population

9 patients (3 women; mean age 59 +/- 11 years) with atrial fibrillation (AF) and atrial flutter (AFL) who developed dissociation of conduction between the coronary sinus (CS) and posterior left atrium (LA) during spontaneous AF and AFL.

Intervention

Electrophysiologic mapping of the LA, CS, and right atrium (RA) using multipolar and basket catheters, along with rapid atrial pacing from the proximal CS and extrastimuli.

Outcome

Dissociation of conduction between the coronary sinus and posterior left atrium.surrogate

Conduction between the coronary sinus and posterior left atrium can be dissociated during spontaneous atrial arrhythmias and provocative proximal CS pacing, challenging the assumption that CS recordings always represent LA activity.
