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 ...

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

ATHENS, GREECE — Suppression of frequent premature ventricular contractions (PVCs) in patients with systolic heart failure could help raise LV contractile function enough possibly to make a ...

Common extra heartbeats known as premature ventricular contractions (PVCs) may be a modifiable risk factor for congestive heart failure (CHF) and death, according to researchers at UC San Francisco.

Stress and anxiety can trigger premature ventricular contractions (PVCs), a type of arrhythmia. Premature ventricular contractions (PVCs) can be caused by emotional stress and anxiety, among other ...

The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of ...

The research team quantified premature atrial contractions (PACs) and premature ventricular contractions (PVCs) in the 1414 individuals who were randomly assigned to have 24-hour Holter monitors.
