What is a sinus rhythm with occasional premature ventricular complexes?

Sinus rhythm with occasional premature ventricular complexes (PVCs) is a heart rhythm disorder in which the heartbeats originate in the sinoatrial node (SA node), as in normal sinus rhythm, but are occasionally interrupted by premature beats that originate in the ventricles (the lower chambers of the heart). These premature ventricular beats can cause a skipped heartbeat or an extra heartbeat, which can be felt as a skipped or extra beat in the chest.

PVCs are a common heart rhythm disorder, and they are usually not a cause for concern. However, frequent or sustained PVCs can be a sign of an underlying heart condition, such as coronary artery disease or heart failure. In some cases, PVCs can also lead to more serious heart rhythm disorders, such as ventricular fibrillation.

If you are experiencing frequent or sustained PVCs, it is important to see a doctor to rule out any underlying heart conditions and to determine if treatment is necessary. Treatment for PVCs may include medications, lifestyle changes, or ablation therapy to destroy the tissue that is causing the PVCs.
