Premature ventricular complexes or contractions (PVCs) are extra heartbeats that can disturb the rhythm of the heart. Learn more here.

Unlike premature atrial contractions, or PACs, usually narrow-complexed because they use the normal ventricular conduction system (unless a baseline right or left bundle branch block is present).

DEAR DR. ROACH: What’s the difference between atrial fibrillation and premature ventricular contractions, aka PVCs (extra heartbeats)? -- M. ANSWER: Both AFib and PVCs are rhythm disturbances of ...

It’s known as a premature ventricular contraction (PVC, also premature ventricular complex). When PVC happens in a pattern of three beats, doctors call it trigeminy. It can feel like fluttering ...

Premature ventricular contractions (PVCs) can be caused by emotional stress and anxiety, among other factors. PVCs are a common type of arrhythmia (irregular heartbeat) that may cause you to feel ...

Premature ventricular contractions (PVCs) are common, but is it safe to exercise if you experience them? It depends on how often you have them and how exercise impacts them. Learn more.

After every routine beat, you have a beat that comes too early, or what's known as a premature ventricular contraction (PVC). PVCs are common and not always harmful. If you're in good health, you ...

Premature atrial contractions originate in the upper chambers and typically pose little risk. Premature ventricular contractions start in the lower chambers and occur in up to 75% of healthy people.

Just a dozen patients have undergone the new treatment that uses electrical pulses to target problem areas inside the heart.

In all cases ventricular tachycardia, idioventricular rhythm or frequent premature ventricular contractions (more than 6 per minute) had developed as the indication for treatment with lidocaine.

Figure 1. Illustrative tracings of resetting of a pacemaker rhythm and of a reentrant arrhythmia. Upper and mid panels: a premature ventricular contraction occurs during a pacemaker rhythm: if it ...

Those were PVCs - Premature Ventricular Contractions. Dr Edmond Cronin, a Temple Health electrophysiologist, says heart beats normally begin in the upper chambers of the heart.
