Objective The natural history of frequent premature ventricular complexes (PVCs) in association with preserved left ventricular ejection fraction (LVEF) is uncertain. The optimal management of this ...

Although premature ventricular beats (PVBs) in young people and athletes are usually benign, they may rarely mark underlying heart disease and risk of sudden cardiac death during sport. This review ...

The overall mortality rate for patients with competitive rhythm (either premature ventricular contractions or the return of sinus rhythm) was 30 per cent (6 of 20) as opposed to 10 per cent (2 of ...

In 1 transient hypotension developed, with a ventricular rate of 30, shortly after the administration of 100 mg. of diphenylhydantoin for ventricular premature contractions.

The prevalence of frequent premature ventricular complexes (PVCs >30/h) is estimated to be around 6% in middle-aged individuals. [60] PVCs have been associated with higher incidence of AF, [61, 62 ...

Cather ablation of parahisian premature ventricular complexes (PVCs) often requires ablation in multiple cardiac chambers, including the sinuses of Valsalva (SoV). The safety and efficacy of ablation ...

Premature ventricular complexes (PVCs) are irregularities in heart rhythm where the ventricles contract earlier than expected, disrupting the normal cardiac cycle. Identifying the origin of PVCs ...

Premature ventricular complexes are the most common ventricular arrhythmias in the structurally normal heart. Although premature ventricular complexes can have a detrimental effect on the quality of ...

The term heart rate turbulence (HRT) was coined to describe the short-term fluctuation in sinus cycle length (SCL) that follows a ventricular premature complex (VPC). 1 In normal subjects, sinus rate ...

A wide QRS complex (0.14 sec) (^) follows most of the sinus complexes; it has a different morphology and is not preceded by a P wave. These are premature ventricular complexes.
