Premature ventricular contractions (PVCs) - Mayo Clinic
2022年4月30日 · Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the heart's two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a sensation of a fluttering or a skipped beat in the chest.
When to worry about premature ventricular contractions (PVCs)
2022年7月1日 · Premature atrial contractions, or PACs, are when the top part of the heart (atrium) contracts before making a complete beat. With PVCs, the bottom part of the heart (ventricle) contracts too...
Premature Ventricular Contractions (PVCs) - Cleveland Clinic
Premature ventricular contractions (PVCs) are a type of irregular heartbeat. They occur when the electrical signal to start your heartbeat comes from your lower heart chambers. PVCs are common and usually aren’t dangerous.

2023年12月25日 · What Are Premature Ventricular Contractions (PVCs)? If your heart feels out of rhythm or “flutters,” especially when you're anxious or stressed, it could be caused by premature ventricular...
Premature ventricular contraction - Wikipedia
A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node. PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest.
Premature Contractions ‒ PACs and PVCs | American Heart ...
2024年9月24日 · Premature beats that start in your heart’s upper chambers are premature atrial contractions, or PACs. Those that start in the lower chambers are premature ventricular contractions, or PVCs. Watch an animation of a normal heartbeat. They can happen to anyone but are more often found in older adults.
Premature ventricular contractions (PVCs) - Mayo Clinic
2022年4月30日 · Most people with premature ventricular contractions (PVCs) who don't have heart disease won't need treatment. If you have heart disease, PVCs can lead to more-serious heart rhythm problems (arrhythmias).
