Management of atrial fibrillation in cardiac resynchronization therapyClinical practice of CRT: how to improve the success rate
Why the study?
Does electrical cardioversion followed by AV sequential biventricular pacing restore and maintain sinus rhythm and improve functional capacity in CRT candidates with permanent atrial fibrillation?

Implication
Should not yet change AF management in CRT candidates; hypothesis-generating for rhythm restoration benefits.
Structured PICO
Does electrical cardioversion followed by AV sequential biventricular pacing restore and maintain sinus rhythm and improve functional capacity in CRT candidates with permanent atrial fibrillation?
P
Population
30 patients with severe congestive heart failure, inter- and intraventricular conduction delay, and atrial fibrillation (onset at least 6 months earlier) selected for cardiac resynchronization therapy (CRT).
I
Intervention
Electrical cardioversion followed by placement of an additional atrial electrode during CRT device implantation to ensure AV sequential biventricular pacing, along with antiarrhythmic medication.
O
Outcome
Restoration and maintenance of sinus rhythmsurrogate
Electrical cardioversion followed by AV sequential biventricular pacing is feasible and effective for restoring and maintaining sinus rhythm in CRT candidates with long-standing atrial fibrillation, leading to improved ejection fraction and functional capacity.
