Arrhythmia: Bigeminal PVC Explained

What is the term for a premature ventricular contraction (PVC) that occurs every other beat?

A premature ventricular contraction that occurs every other beat is known as a bigeminal PVC.

Are you curious about what happens when the heart experiences a premature ventricular contraction (PVC) every other beat? Let's dive into the exciting world of cardiac arrhythmias and explore the fascinating phenomenon of bigeminal PVC!

What is Bigeminal PVC?

Bigeminal PVC is a specific type of arrhythmia where premature ventricular contractions (PVCs) occur every other beat. These PVCs disrupt the normal rhythm of the heart and can be caused by various factors such as ectopic pacemakers or ectopic foci.

Causes of Bigeminal PVC

Bigeminal PVC can be triggered by conditions like localized ischemia, certain substances (e.g., caffeine), medications (e.g., digitalis), or heightened activity of the autonomic nervous system. These factors can stimulate ectopic foci in the heart, leading to the occurrence of PVCs in a bigeminal pattern.

Significance of Bigeminal PVC

While occasional PVCs are generally considered harmless, persistent or chronic occurrences of bigeminal PVCs can potentially result in more serious arrhythmias or even fibrillation. Therefore, it is important to monitor and address any abnormal heart rhythms, including bigeminal PVCs, to prevent potential complications.

Overall, the world of cardiac arrhythmias is complex and fascinating, and understanding conditions like bigeminal PVC can help individuals take proactive steps to maintain heart health and well-being. Stay informed and consult with healthcare professionals for any concerns about your heart rhythm!
