What does AVB mean in PHYSIOLOGY

What Does AVB Stand For?

AVB stands for Atrioventricular Bundle. It is a group of nerve fibers that carries electrical impulses from the atria—the upper chambers of the heart—to the ventricles—the two lower chambers of the heart that pump blood throughout the body. This bundle of fibers is also known as the Bundle of His and forms what’s known as an electrical conduction system that regulates heartbeat patterns in humans and other higher mammals.

What Is The Full Form Of AVB?

The full form of AVB is Atrioventricular Bundle. It’s also known as the Bundle of His, which comes from its namer, Wilhelm His Jr., a 19th-century German anatomist who studied human anatomy under Rudolf Virchow. The term AV bundle was first used in 1901 by Carl Kuehne to refer to this bundle of nerves in human hearts.

Importance In Medical Field

In addition to regulating heartbeat patterns, the AV bundle has several important functions within cardiac physiology. Because it serves to coordinate activities between different parts of the heart muscle, it plays a critical role in maintaining cardiac rhythmicity during exercise or stress; thus, any disruptions or abnormalities can potentially lead to fatal arrhythmias or cardiac arrest. Additionally, since it connects a variety of signals from both sides of the heart, it also plays an important part in assessing certain blood pressures within each chamber respectively. Therefore, when diagnosing any number of cardiac conditions like hypertrophic cardiomyopathy or pulmonary stenosis, physicians will often check how signals are being conducted through this bundle before making their diagnosis official.
