The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of ...

Lead II is frequently unrepresentative of QRS configurations, especially for arrhythmias. Here, there is atrial bigeminy due to premature atrial complexes. Although the last QRS in lead II is ...

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 ...

Ventricular bigeminy occurs when every other beat is a PVC. No treatment is necessary for PVCs. If symptomatic, beta-blockers or antiarrhythmic drugs can be effective. Rarely, ablation of PVCs is ...
