PVCs: Causes and Associated Conditions

Premature Ventricular Contractions (PVCs) are irregular heartbeats that start in the ventricles of the heart rather than in the sinoatrial (SA) node. They can feel like a fluttering or skipped beat in your chest.

The most common causes of PVCs include high levels of adrenaline due to anxiety, stress, strenuous exercise, or certain medications. Excessive intake of caffeine or alcohol can also trigger PVCs. People with certain underlying medical conditions, such as heart disease, high blood pressure, or valve disease, are more prone to experiencing PVCs.

It is important to consult with a healthcare provider if you have frequent PVCs or if they are accompanied by symptoms such as dizziness, chest pain, or fainting. Your doctor can determine the underlying cause of your PVCs and recommend appropriate treatment.
