idionodal

idionodal
Arising from the AV node itself; applied to the ventricular rhythm in complete S-A or AV block, or in other forms of AV dissociation, when the AV node rather than an ectopic ventricular focus controls the ventricles. More accurately idiojunctional, since it is usually impossible to more accurately locate an “AV nodal” rhythm; the AV node is part of the AV junction. SEE ALSO: idioventricular.
