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 ...

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 ...

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 ...

Background A 44-year-old female presented with a long history of chest pain, palpitations and increasing dyspnea. Electrocardiography and 24 h Holter monitoring revealed multiple premature ventricular ...

THE diagnosis of ventricular tachycardia without retrograde activation of the atrium is dependent upon the location of regular atrial activity that is independent of the faster ventricular rate. The ...

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 ...

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 couple of neat Apple Watch stories popped up on Reddit recently. One user shared how his Apple Watch Series 4 caught a premature ventricular contraction and was able to quickly share the results ...
