What is the most appropriate initial management for a patient presenting with symptomatic bradyarrhythmia?
Administration of atropine
In a symptomatic bradyarrhythmia (hypotension, altered sensorium, chest pain), the first-line pharmacological therapy per ACLS is intravenous atropine (0.5 mg every 3–5 min, maximum 3 mg), which blocks vagal tone and increases the SA nodal firing rate.
Diuretics lower volume and worsen hypotension, defibrillation treats tachyarrhythmias (VF/VT), and oral anticoagulants have no role in an acute bradycardia.
Hence, Administration of atropine.
