If atropine is ineffective in treating bradycardia, what is the recommended second line treatment?

• A. Adenosine
• B. IV glucagon
• C. Trial pacing
• D. Electrophysiology consultation

Answer: (C)

The recommended second line treatment when atropine is ineffective in treating bradycardia is trial pacing. In the context of advanced life support, when bradycardia is symptomatic or causes hemodynamic instability, atropine is often the first medication administered. However, if there is no response, it is critical to escalate the management effectively to ensure patient safety and improvement of heart rate. Trial pacing involves the use of transcutaneous pacing, which delivers electrical impulses to stimulate the heart and increase the heart rate manually. This technique allows for rapid correction of the bradycardia and can be easily performed in emergency situations, providing a temporary solution until a more definitive treatment can be identified or until the underlying cause of the bradycardia is addressed. Other options such as adenosine, IV glucagon, or an electrophysiology consultation would not be the next step in a case where there is persistent bradycardia unresponsive to atropine. Adenosine is typically used for certain types of tachycardia rather than bradycardia, glucagon is not indicated for bradycardia, and an electrophysiology consultation is a more specialized intervention that is not appropriate for immediate management of acute symptomatic bradycardia. Thus,
