VA conduction
VA Conduction
VA Conduction (pronounced as V-A Conduction) is a term used in the field of Cardiology to describe the process of electrical impulses traveling from the ventricles to the atria in the heart. This is the opposite of the normal AV conduction, where the electrical impulses travel from the atria to the ventricles.
Etymology
The term "VA Conduction" is derived from the first letters of the words Ventricles and Atria, which are the two main types of chambers in the heart. The term "conduction" refers to the transmission of electrical impulses.
Related Terms
- Retrograde conduction: This is a type of VA conduction where the electrical impulses travel in the opposite direction to the normal flow, i.e., from the ventricles to the atria.
- Anterograde conduction: This is the normal flow of electrical impulses in the heart, i.e., from the atria to the ventricles. It is the opposite of VA conduction.
- AV node: This is a part of the heart's electrical system that slows down the electrical signal before it enters the ventricles. This delay ensures that the atria have ejected their blood into the ventricles first before the ventricles contract.
- Bundle of His: This is a part of the electrical conduction system of the heart that transmits electrical impulses from the AV node to the point of the apex of the fascicular branches.
