Premature ventricular contraction
(Redirected from Ventricular premature complex)
Premature ventricular contraction (PVC) is a relatively common event where the heart has a heartbeat that is not initiated by the sinoatrial node, the natural pacemaker of the heart where normal heartbeat is initiated. It is caused by an impulse from a ventricular focus.
Causes[edit | edit source]
PVCs may be caused by heart disease, stress, exercise, caffeine, certain medications, and alcohol. They may occur in healthy individuals and are sometimes found during routine ECG examinations.
Symptoms[edit | edit source]
PVCs are typically asymptomatic, but they can cause heart palpitations, and in severe cases, they may lead to cardiomyopathy.
Diagnosis[edit | edit source]
PVCs can be diagnosed through an ECG, Holter monitor, or event monitor. The ECG will show a premature beat, and the following beat will be a compensatory pause.
Treatment[edit | edit source]
Treatment for PVCs is typically not necessary unless they are causing significant symptoms or are linked to other forms of heart disease. In such cases, treatment may include medications, lifestyle changes, or in severe cases, catheter ablation.
Prognosis[edit | edit source]
The prognosis for individuals with PVCs is typically good, especially in those without other heart disease. However, frequent PVCs or certain patterns of them may be a sign of an increased risk of death.
