Accessory pathway
Accessory pathway
Accessory pathway (/əkˈsesəri/ /ˈpāTHˌwā/) is a term used in cardiology to describe an additional conduction pathway or route between the atria and the ventricles of the heart. This pathway is not present in a normal heart and can lead to conditions such as Wolff-Parkinson-White syndrome.
Etymology
The term "accessory pathway" is derived from the Latin "accessorius" meaning additional, and the English "pathway" meaning route or way. It was first used in medical literature in the 20th century to describe abnormal conduction pathways in the heart.
