In complete heart block, what is the typical initial management for acute symptomatic cases?

• A. Vagal maneuvers
• B. Temporary pacing followed by permanent pacemaker
• C. Immediate cardioversion
• D. Observation only

Answer: (B)

Complete heart block means the ventricles beat on their own slow escape rhythm, so when symptoms appear the priority is to restore reliable heart pacing and perfusion. Temporary pacing provides immediate, controllable ventricular pacing in the acute setting, stabilizing the patient and acting as a bridge to definitive therapy. Once stabilized, a permanent pacemaker is placed to correct the conduction failure and prevent recurrent bradycardia. Vagal maneuvers won’t reliably overcome a complete block and are unlikely to improve cardiac output. Immediate cardioversion is reserved for unstable tachyarrhythmias, not a bradycardic block. Observation alone risks ongoing hypoperfusion and deterioration.
