Atrial fibrillation and AV block II?

[Arveno]

Is it possible to have atrial fibrillation and AV block II? Cardiologist whom we visited yesterday say no it is not possible. But ecg with automatic evaluation say definitely pathologic ecg, AV block II. According to another by phone consulted cardiologist it indicate need of pacemaker. Your comments and opinion would be highly appreciated. Thank You.
