AV CONDUCTION Meaning and
Definition
-
Av conduction refers to the process in which electrical signals are conducted through the atrioventricular (AV) node, a specialized structure in the heart. The AV node is located between the atria (upper chambers) and the ventricles (lower chambers) of the heart. Its main function is to delay the electrical impulse from the atria before allowing it to pass through to the ventricles.
During normal cardiac conduction, an electrical signal is generated by the sinus node in the right atrium. This signal then travels through the atria, causing them to contract. When the electrical impulse reaches the AV node, it is momentarily delayed. This delay allows the atria to fully contract, ensuring efficient blood flow to the ventricles.
After the delay, the electrical signal is conducted through the AV node and transmitted to the ventricles. The ventricles then contract, pumping blood out of the heart and into the rest of the body. This coordinated sequence of electrical signals and contractions ensures proper cardiac function and effective circulation.
Disruptions or abnormalities in AV conduction can lead to various cardiac conditions, including heart block or atrioventricular block. In these conditions, the electrical signals may be delayed or blocked as they travel through the AV node, resulting in an abnormal heart rhythm and potential symptoms such as dizziness, fatigue, or fainting.

Etymology of AV CONDUCTION
The term "av conduction" is derived from the combination of two words: "AV" and "conduction".
1. AV: In this context, it stands for "atrioventricular", referring to the connection between the atria and ventricles of the heart. The term "atrioventricular" is a combination of "atrium", which refers to the upper chambers of the heart, and "ventricle", which refers to the lower chambers of the heart.
2. Conduction: It originates from the Latin word "conductio", which means "leading, guidance". In the medical field, it specifically relates to the transmission or propagation of electrical impulses through the tissues.
Together, "AV conduction" refers to the electrical transmission or conduction of the signals between the atria and ventricles of the heart, which is necessary for proper coordination and contraction of the heart muscle.
