Overview
Third-degree or complete atrioventricular block suggests no conduction at all from atria to ventricles and may be paroxysmal or persistent and is usually associated with either a junctional or ventricular escape rhythm. Complete atrioventricular block may be identified in the setting of atrial fibrillation when the ventricular response is slow (<50 bpm) and regular. However, junctional rhythm in the setting of atrioventricular block may be present.
