The mechanisms are currently elusive. Premature complexes (both atrial and ventricular) may be independently with stroke – there is a paucity of data on this relationship and its mechanisms ...

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 ...

A premature atrial contraction (PAC ... refractory), a non-sinus P wave will be seen that is not followed by a QRS complex (non-conducted). There are four main characteristics of PACs: They ...

Sinus rhythm with atrial premature complexes and sinus rhythm with artifacts were particularly susceptible to misinterpretation by the computer algorithm; Bogun et al. recommend that the over ...

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 ...

Arrhythmias evaluated include sinus rhythm, atrial fibrillation, atrial flutter, and sinus with premature ventricular contraction (PVC) or premature atrial contraction (PAC). About HeartBeam ...
