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.

Furthermore, the proportion of time in sinus rhythm whilst on assigned antiarrhythmia therapy did not effect these outcomes in the 1,316 patients for whom electrocardiograms were available.

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 ...
