An automated external defibrillation (AED) device includes a wireless interface to exchange data with one or more other devices. The AED device collects patient data associated with a patient and identifies, based on the patient data, a heart condition associated with the patient. The AED device directs a user to apply defibrillation to the patient to address the heart condition； and forwards via the wireless interface, a notification to a dispatch device. The notification may identify, for example, a location associated with the AED device. The dispatch device may direct emergency medical assistance to the location. The AED device may collect data, used to diagnose the heart condition, from a patient device and via the wireless interface. The AED device may further forward, to a user device and via the wireless interface, instructions guiding the user to use the AED device.
