Should You Have an In-Home AED if You Have an ICD?

Author: Marcy Burnham, RN

For individuals living with an Implantable Cardioverter Defibrillator (ICD), the thought of adding an Automated External Defibrillator (AED) at home might raise questions. Is it necessary? Does it offer added protection? 

Let’s explore the benefits of having an in-home AED for patients who already have an ICD, to help patients, families, and caregivers make an informed decision about cardiac preparedness at home.

1. Backup if the ICD Fails or Malfunctions

While rare, ICDs can fail—whether due to battery depletion, lead fractures, or programming errors. In such instances, having a home AED provides a life-saving backup if sudden cardiac arrest (SCA) occurs and the ICD does not respond appropriately.

2. Protection for Others in the Home

An AED isn’t just for the ICD patient. If family members or caregivers also have underlying heart conditions or risks, the AED can be a valuable resource for the whole household.

3. Added Peace of Mind

Knowing there’s an AED nearby can provide emotional reassurance for patients and loved ones. This psychological safety net can help reduce anxiety and promote peace of mind during daily life.

4. Supports Emergency Response

In some emergencies, ICDs may deliver multiple shocks, but the patient may not regain consciousness or maintain a viable rhythm. In these scenarios, external defibrillation and CPR may still be necessary—and having an AED available ensures immediate action while awaiting EMS.

5. Improved Outcomes in High-Risk Scenarios

Patients with a history of frequent arrhythmias, heart failure, or prior cardiac arrest may benefit from a layered approach to cardiac care. An AED ensures that first responders or family members can act quickly, even if the ICD initiates therapy.

An ICD is a powerful tool to prevent sudden cardiac death—but having an in-home AED can offer an extra layer of security when every second counts. For those living with or caring for someone with a heart condition, open conversations with a cardiologist or electrophysiologist can help determine whether this investment makes sense.

If you decide to move forward with an AED, make sure your household is trained in CPR, familiar with the device, and ready to act. Because when it comes to sudden cardiac arrest, preparedness saves lives.
