2024年10月8日 · A premature ventricular complex (PVC) is a premature beat arising from an ectopic focus within the ventricles. AKA: ventricular ectopics, ventricular extrasystoles, ventricular premature beats, ventricular premature depolarisations. ECG features of PVCs

2020年4月27日 · Premature ventricular complexes (PVCs) are extremely common, found in the majority of individuals undergoing long-term ambulatory monitoring. Increasing age, a taller height, a higher blood pressure, a history of heart disease, performance of less physical activity, and smoking each predict a greater PVC frequency.

2019年6月4日 · Outflow tract ventricular arrhythmias (OTVAs) are the most common type of idiopathic VA. It typically presents in young patients—and has a notably increasing incidence. 1 It is classically a benign, focal arrhythmia but patients can be highly symptomatic and refractory to medical therapy.

A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node. PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest. PVCs do not usually pose any danger. [1]

2023年8月8日 · During a premature ventricular contraction (PVC), the heartbeat is initiated by the Purkinje fibers rather than the SA node. Given that a PVC occurs before a regular heartbeat, there is a pause before the next regular heartbeat. PVCs can occur in isolation or in repeated patterns.

When every other beat on the ECG is a premature ventricular complex (PVC), the rhythm is referred to as PVC in bigeminy (Figure 3). If every third beat is a PVC, it is referred to as PVC in trigeminy .

Premature ventricular complexes (PVCs) (also known as ventricular premature complexes [VPCs]) are ectopic impulses originating from an area distal to the His Purkinje system. PVCs...

2021年10月5日 · Premature ventricular contractions (PVCs) in the absence of structural heart disease (SHD), or inherited ion channelopathies, are referred to as idiopathic and are among the most common arrhythmias encountered in everyday clinical practice.

Catheter ablation is effective and safe treatment for these patients. β blockers may be used for symptom control in patients where VEBs arise from multiple sites. It should also be considered in patients with impaired ventricular systolic function and/or heart failure.
