A patient with an implanted AICD is unresponsive with no pulse. What should the dispatcher instruct?

• A. Remove clothing to locate device
• B. Delay care until paramedics arrive
• C. Attempt to interrogate the device at the scene
• D. Begin CPR and use AED as soon as available

Answer: (D)

In cardiac arrest, the priority is immediate high-quality CPR and defibrillation with an AED as soon as it’s available. An implanted AICD does not replace this need and should not delay care or be interrogated at the scene. Start CPR right away to maintain perfusion, then apply the AED and follow its prompts. If a pad placement decision is needed because an implanted device is present, place the pads so the shock path avoids the device. This approach maximizes chances of survival and minimizes delays.
