We suggest that patients requiring pacing for the treatment of symptomatic bradycardia secondary to sinus node dysfunction, atrial or dual-chamber pacing be generally used for the prevention of AF. (Recommendation Conditional, Quality High)<br /><br />We suggest that, in patients with intact AV conduction, pacemakers be programmed to minimize ventricular pacing for prevention of AF. (Recommendation Conditional, Quality Moderate)<br /><br /><b>Values and preferences: </b>These recommendations recognize a potential benefit of atrial or dual-chamber pacing programmed to minimize ventricular pacing to reduce the probability of AF development following pacemaker implantation.
