Cardiologic consultation is indicated for all patients with third-degree atrioventricular (AV) block (complete heart block). The consultation is emergent in patients with concomitant acute myocardial infarction (MI), active myocardial ischemia, congestive heart failure, wide-complex escape rhythm, or symptoms of hypoperfusion. Patients in this group may require early placement of a permanent pacemaker, or assistance may be needed if difficulty is encountered obtaining capture from an external or transvenous pacer.

The involvement of an electrophysiologist should also be considered when appropriate.
