impaired electrical conduction between the atria and ventricles
Atrioventricular blockWhat is First-degree heart block?
PR interval > 0.2 seconds
Atrioventricular blockWhat is Second-degree heart block, type 1?
progressive prolongation of the PR interval until a dropped beat occurs
Atrioventricular blockWhat is Second-degree heart block, type 2?
PR interval is constant but the P wave is often not followed by a QRS complex
Atrioventricular blockWhat is Wenckebach heart block?
Second-degree heart block, type 1 (Mobitz I)
Atrioventricular blockWhat is Third-degree (complete) heart block?
