creating a wide QRS complex. Unlike premature atrial contractions, or PACs, usually narrow-complexed because they use the normal ventricular conduction system (unless a baseline right or left ...

A premature ventricular contraction ... scheduled sinoatrial nodal action potential. Ventricular bigeminy occurs when every other beat is a PVC. No treatment is necessary for PVCs.

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 ...

1 This editorial presents the rationale and considerations for a period of detraining in the diagnostic evaluation of athletes with premature ventricular beats (PVBs). Ultrastructural changes related ...

Catheter ablation was performed in order to eliminate the trigger of the patient's ventricular arrhythmias and prevent future episodes of syncope. With the precise underlying mechanisms of VF ...
