There are four main characteristics of premature ventricular contractions: Premature, occurring earlier than expected if measured against previous R-R intervals.

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.

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.

A similar condition -- premature ventricular contraction (PVC) -- starts in the lower chambers, called “ventricles,” of your heart. Any time your heart shifts out of its usual rhythm, doctors ...

Background and objective Prior studies have suggested that patients with premature ventricular complexes (PVCs) may have an ...

Medically reviewed by Jeffrey S. Lander, MD Bigeminy is an irregular heart rhythm where every normal beat is followed by an abnormal one, often due to premature ventricular contractions (PVCs). 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.

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.

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 ...
