Welsh Ambulance Service plans to use drones to deliver defibrillators to heart attack victims.
Defibrillators are used with CPR to increase chances of survival after cardiac arrest.
Over 6,000 cardiac arrests happen annually in Wales.
Drones could be especially helpful in reaching patients in rural areas.
The Drone-Delivered Defibrillators study conducted "test flights" to estimate how quickly a defibrillator could be deployed after a 999 call.
The project will interview people who helped cardiac arrest victims to improve future procedures.
Study by University of Warwick, and findings are expected in early 2025.
