To maintain sinus rhythms, atrial pacing algorithms ... of atrial substrate and suppress AF triggers, including premature atrial contractions (PACs), believed to be a primary inducer of AF.

Thus it must "skip a beat" and it will resume exactly 2 P to P intervals after the last normal sinus beat. When every other QRS complex is a PAC, then the rhythm is referred to as "atrial bigeminy".

When every other QRS complex is a premature atrial contraction, then the rhythm is ... thinking that sinus bradycardia is present, because every other beat is a nonconducted PAC, and the QRS ...
