Correct answer: E — Atropine 500 micrograms intravenously, repeated as needed.

Symptomatic bradycardia with adverse signs is treated with atropine 500 micrograms intravenously, repeated to a maximum of 3 mg, with consideration of second-line measures if it fails. A single 3 mg dose is excessive as a first step. Adenosine and amiodarone are used for tachyarrhythmias rather than bradycardia.
