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.

2024年2月8日 · PVCs (a heart arrhythmia) are generally only dangerous in those with heart conditions, such as heart disease. Learn when to worry about PVCs and how they are treated.

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...

2022年7月29日 · 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. Your risk of complications increases if you have another heart condition, such as heart disease or a congenital heart defect.

2025年1月8日 · Premature ventricular contractions (PVCs) are early heartbeats that start in the lower chambers of the heart (ventricles). They disrupt the heart's normal sinus rhythm, often creating a sensation of a skipped or extra beat.

2024年3月19日 · Premature ventricular contraction (PVC) is a type of abnormal heartbeat, or arrhythmia. It happens when the heartbeat begins in the lower, rather than the upper, heart...

2024年10月31日 · Premature ventricular contractions (PVCs) are a type of irregular heart rhythm commonly experienced by many people. Often described as a “skipped beat” or a “fluttering sensation” in the chest, PVCs can cause concern, particularly when they are frequent.

PVCs can happen in people without any heart disease, but they're more common in people with some kind of heart disease. PVCs rarely cause problems unless they occur again and again over a long period of time. In such cases, they can lead to a PVC-induced cardiomyopathy, or a weakening of the heart muscle from too many PVCs.

In most cases, PVCs are benign and do not pose a threat to heart health, especially in individuals without underlying heart disease. However, frequent PVCs can have significant consequences: Heart muscle weakening: Very frequent PVCs (e.g., >10,000 per day) can cause PVC-induced cardiomyopathy, where the heart becomes weakened over time.

Premature Ventricular Contractions (PVCs) are early heartbeats originating in the heart’s lower chambers, called the ventricles. PVCs disrupt the normal heart rhythm, causing a sensation of a skipped beat or a fluttering in the chest. Although often harmless, frequent PVCs may …
