What is the protocol for regular narrow complex tachycardia?

• A. Expedite transport only
• B. Perform supportive care and expedite transport
• C. Initiate synchronized cardioversion
• D. Administer adenosine

Answer: (B)

Regular narrow complex tachycardia indicates a supraventricular rhythm in a patient who is currently stable. The safest and most appropriate action is to stabilize the patient on scene and arrange rapid transport to a facility where definitive management can be provided. This means continuous monitoring, ensuring airway and breathing are adequate, establishing IV access, administering oxygen if needed, and addressing any symptoms or discomfort while preparing for transfer. Cardioversion is reserved for unstable patients, and giving a drug like adenosine in the field carries risks and is not the chosen course in this protocol for a stable presentation. By focusing on supportive care and getting the patient to the appropriate setting quickly, you maximize safety and ensure access to the full range of therapies available in a monitored environment.
