A definition of the AV node applying to anatomic and functional studies, along with orthogonal topographic representation, is proposed to better understand its structure-function relationship.
The anatomic and functional substrate underlying AV nodal rate-dependent and dual pathway properties remains highly controversial. This article focuses on some factors that impair the understanding of the AV nodal structure-function relationship and some clues toward sorting it out. A definition of the AV node that applies to both anatomic and functional studies, an orthogonal topographic representation of nodal structures, and the integration of rate-dependent and dual pathway behavior of the AV node are proposed as primary steps toward a better understanding of the AV nodal structure-function relationship. Further fact-based information is the key to the sorting out of this puzzle.
Jacques Billette (Wed,) conducted a review in Atrioventricular nodal structure-function relationship. A definition of the AV node applying to anatomic and functional studies, along with orthogonal topographic representation, is proposed to better understand its structure-function relationship.
