Atrioventricular (AV) block is partial or complete interruption of impulse transmission from the atria to the ventricles. The most common cause is idiopathic fibrosis and sclerosis of the conduction system. Diagnosis is by electrocardiography; symptoms and treatment depend on degree of block, but treatment, when necessary, usually involves pacing. The condition is also called atrioventricular (AV) block.

First degree AV block; Second degree AV block; Second degree AV block, type I; Second degree AV block, type II; Third degree atrioventricular block or complete atrioventricular block AV-block III (totalt AV-block, AV-dissociation) Vid AV-block III överleds inga impulser från förmak till kammare. Då föreligger så kallad atrioventrikulär dissociation (AV-dissociation). Patienten överlever om en ersättningsrytm (med ursprung distalt om hindret) uppkommer.
Vanligt EKG kan sällan avslöja var AV-blocket är lokaliserat men ibland finns det indikationer om var det sitter: Vid AV-block II typ I, d v s med s k Wenckebach-periodik, är lokaliseringen så gott som alltid i AV-knutan och QRS-komplexet är därför smalt och tillståndet oftast benignt. Ett exempel är hjärtborrelios.
