A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential. Premature, occurring earlier than ...

Premature ventricular contraction (PVC) is a type of abnormal heartbeat, or arrhythmia. It happens when the heartbeat begins in the lower, rather than the upper, heart chambers. This creates an ...

Idiopathic premature ventricular contractions (PVCs) may cause subtle changes in left atrium (LA) structure and function. The authors of an article published in Cardiovascular Innovations and ...

A healthy 33-year-old woman with no cardiac risk factors feels thumps or skipped beats in her chest a few times a day regardless of activity. An event recorder showed premature ventricular ...

An independently validated risk score may help predict adverse events in patients with frequent premature ventricular contractions (PVCs), new research suggests. Over the past decade, there has been ...

WASHINGTON, DC — A higher percentage of premature ventricular contractions (PVCs) predicted a dropoff in LV ejection fraction and a greater risk of incident heart failure and mortality in a long-term ...

Between Sept 1982 and Oct 1984, we diagnosed premature ventricular contractions(PVCs) in 9 newborns and infants (3M/6F). CXRs were obtained in 6 patients(pts) and ...

Palpitations due to premature beats, either ventricular contractions (PVCs) or atrial contractions (PACs), can be extremely vexing even when we know they are benign. For many individuals, these ...

Q: About 15 years ago, while giving blood, I was advised of an irregularity, which my doctor confirmed after an EKG, known as premature ventricular contractions. He told me not to worry, and I've not ...
