Atropine for Bradycardia | ACLS Certification Association

Understand atropine's role in symptomatic bradycardia and the treatment options discussed when it is ineffective. Review the key concepts in this focused ACLS lesson. CLINICAL CORRECTION: This recording contains outdated medication doses. The 2025 AHA adult bradycardia algorithm specifies atropine 1 mg IV, repeated every 3–5 minutes to a maximum total of 3 mg, and dopamine infusion at 5–20 mcg/kg/min, titrated to response. In this lesson, we'll review: ▪️How atropine blocks parasympathetic influences on heart rate and AV conduction ▪️Atropine limitations, AV blocks, and myocardial ischemia precautions ▪️Transcutaneous and transvenous pacing ▪️Dopamine and epinephrine as alternative medications For nurses, paramedics, physicians, respiratory therapists, and healthcare students reviewing adult bradyarrhythmias.
