Medication Summary

In general, complete heart block is not amenable to medications. In emergent situations, for short-term use, catecholaminergic stimulation with isoproterenol infusion may be useful to maintain an adequate escape rate while awaiting placement of a temporary or permanent pacemaker. Medications which cause or exacerbate AV block should be discontinued whenever possible.


Beta1/Beta2 Adrenergic Agonists

Class Summary
