If symptomatic, standard ACLS guidelines for symptomatic bradycardia to include
Atropine 0.5mg IV q3-5min PRN total dose of 3mg
Transcutaneous pacing, followed by transvenous pacing
Dopamine IV consider for low BP 3mcg/kg/minute titrate up to 20 mcg/kg/minute
Dobutamine IV consider for heart failure at 5mcg/kg/minute titrate up to 20mcg/kg/minute if needed for HR and BP augmentation
Treat underlying etiology
Avoid AV nodal blocking agents (e.g. β-blockers)
