Managing bradycardia: what is the recommended initial approach?

• A. Prepare for pacing only
• B. Treat with atropine and prepare for pacing if needed
• C. Observe without intervention
• D. Defibrillate immediately

Answer: (B)

In symptomatic bradycardia, the first goal is to raise the heart rate quickly while you assess why the bradycardia is occurring. The recommended initial approach is to give atropine to block the vagal influence on the heart, improving SA node firing, and to prepare for pacing if atropine doesn’t achieve a sufficient response. Atropine is given IV at 0.5 mg, can be repeated every 3-5 minutes, up to 3 mg total. If the patient remains unstable or there’s evidence of a high-grade or infranodal block, you should move to pacing (transcutaneous first, then transvenous as needed) to maintain an adequate rate. Defibrillation is not indicated for isolated bradycardia, and simply observing without intervention isn’t appropriate when there are symptoms or hemodynamic compromise.
