Premature Ventricular Contraction Complications In most cases, PVCs have no complications. But if you have a lot or have certain patterns of PVCs, your heart muscle can get weaker over time.

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).

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 ...

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 ...

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.

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.

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 ...

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

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 ...

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 ...

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.
