Overview
Correction of reversible causes of the block such as ischemia, medications, and vagotonic conditions should be considered. Treatment may also include medicines to control blood pressure and atrial fibrillation, as well as lifestyle and dietary changes to reduce risk factors associated with heart attack and stroke. Treatment in emergency situations are atropine and an external pacer.
Atropine can partially or completely restore conduction through the AV node when the cause for complete heart block is acute myocardial infarction (ischemia of the AV node). Atropine, in this setting, reverses the reduced conduction across the AV node (which is due to increased vagal tone).
