The AV node is located between [[Atrium,_Vorhof/en|atrium]] and [[Herzkammer/en|ventricle]] of the [[Erregungsbildungs-_und_Leitungssystem/en|excitation conduction system]] of the heart, where the delaying (negative [[dromotrop/en|dromotropic]]e) effect of the [[Vagus/en|vagus]] and the accelerating (positive [[dromotrop/en|dromotropic]]e) effect of the [[sympathetic nervous system] occurs. It is the secondary centre of stimulation in the heart.
