isorhythmic atrioventricular dissociation
- isorhythmic atrioventricular dissociation
- a form of atrioventricular dissociation in which the atria and ventricles beat at similar rates, although independently; it usually results from severe sinus bradycardia in which the sinus node discharge rate drops just below that of the atrioventricular junctional tissue.
