A premature atrial contraction ... 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 referred to as “atrial bigeminy” as seen in this strip above. If a PAC occurs when the AV node has not yet ...

These algorithms target modification of atrial substrate and suppress AF triggers, including premature atrial contractions (PACs), believed to be a primary inducer of AF. Using data from dual ...

Here, there is atrial bigeminy due to premature atrial complexes. Although the last QRS in lead II is slightly larger, the aberrant ventricular conduction in the premature beats is not evident in ...

Single ventricular premature complexes (VPCs), as well as pairs and triplets of VPCs, were observed in the initial and follow-up ECG. VPCs (also called ventricular premature contractions ...
