Customised supermarket trolleys with sensors in the handles have been successfully tested as a way to identify people at risk of stroke.
The trolleys are fitted with electrocardiogram (ECG) technology to detect hidden atrial fibrillation (AF), an irregular heartbeat that is a leading cause of stroke.
The sensors pick up faulty heartbeats by tracking electrical signals from the heart as they pass through the hands.
If the sensors pick up potential signs of AF, a red cross flashes up on the trolley’s handle, while a green tick shows no abnormal signs were detected.
In a trial by Liverpool John Moores University, 2,155 adults used ten customised trolleys at four supermarkets. Participants were instructed to hold the trolley handle for at least 60 seconds continuously while they shopped.
