COR	LOE	RECOMMENDATIONS
1	A	1. In patients with bradycardia requiring cardiac-implanted electronic devices who have normal atrioventricular conduction, device selection and programming strategies to maintain atrioventricular synchrony and minimize ventricular pacing should be used to reduce the incidence and progression of AF. 1-6
2b	B-NR	2. In selected patients with a pacemaker and symptomatic atrial tachyarrhythmias, antitachycardia atrial pacing and ventricular pacing minimization may be useful for reducing symptoms.7-13
2b	C-LD	3. In patients with AF who require significant ventricular pacing, conduction system pacing may be useful to reduce progression of AF.14,15
3: No benefit	B-R	4. In patients with AF, specialized atrial pacing algorithms designed to suppress AF are not useful for reducing the incidence or slowing the progression of AF.12,16-18
