Recommendations for atrioventricular junction ablation in atrial fibrillation

Recommendations	Class	Level of evidence
AF affecting the therapy with ICD, in which other therapies could not be used or were not able to restore/maintain sinus rhythm or control the ventricular frequency	I	C
AF in patients with CRT for optimization of the therapy	IIa	B
AV node ablation with permanent ventricular stimulation is a reasonable strategy for heart rate control in cases when drug therapy is not suitable or when rhythm control is not possible	IIa	C
AV node ablation with permanent ventricular stimulation in clinically well patients	III	C

AF: atrial fibrillation; ICD: implantable cardioverter defibrillators; CRT: cardiac resynchronization therapy; AV: atrioventricular
