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 ...

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 ...

Background Frequent idiopathic premature ventricular contractions (PVCs) have been associated with left ventricular cardiomyopathy. Idiopathic PVCs often originate from the right ventricular outflow ...

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 ...

In the last few weeks, the Skeptical Cardiologist has had a run on with patients with premature atrial contractions (PACs). I've discussed in detail premature ventricular contractions (PVCs) here and ...

People who experience high-grade premature ventricular contractions (PVCs) during the recovery period following exercise may be a higher risk for later cardiovascular mortality, a new study suggests.

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 ...
