Which rhythms are considered normal?

Rhythm normalcy comes from a well-coordinated impulse origin and regular conduction, not just a particular rate. Normal sinus rhythm means the electrical impulse starts in the SA node, so you see a P wave before every QRS with a normal PR interval and a steady rhythm. Accelerated junctional rhythm is a different, junction-origin rhythm that can still be coordinated and without hemodynamic problems: its rate sits around the normal-bracket to slightly elevated range, the QRS is narrow and regular, and P waves may be absent, inverted, or appear after the QRS. In the right clinical context, this can be a benign, stable rhythm, particularly when there are no symptoms and the heart is circulating effectively. So both patterns can be considered normal variants when they show regular, organized conduction and the patient remains hemodynamically stable. Atrial fibrillation, by contrast, is disorganized atrial activity with irregular ventricuar response and is not a normal rhythm.
