Role of pacing mode and algorithms for effective prevention of atrial fibrillation after coronary artery bypass surgery.
Atrial fibrillation after coronary artery bypass surgery occurs in 30 to 40% of patients. Prophylactic therapy with drugs is not always possible and not always efficient. Atrial pacing may play a role in the prevention of atrial fibrillation. Biatrial pacing with fixed high rate or overdrive and right atrial pacing with overdrive has been demonstrated to reduce the incidence of atrial fibrillation after coronary artery bypass surgery. Avoidance of undersensing and loss of capture with atrial epicardial wires is a technical challenge. Individually tailored and combined approaches are promising future directions for prophylactic therapy.
