A Hampshire firefighter has become one of the first people in the world to be fitted with a pioneering device which can monitor a patient's heart activity using their mobile phone.
Retained firefighter Sian Jones underwent the 10 minute procedure at Southampton University Hospital on Friday - the first hospital in the country to carry out the operation.
The device, which is a similar size to a paperclip, was developed at Southampton General Hospital.
It works by sending Bluetooth signals from the device to a mobile phone, in real time.
The 34-year-old was in a car crash when she was 18 and has suffered from blackouts ever since.
It is hoped the device will uncover why it keeps happening.
Two people have so far had the device fitted, with 10 more set to benefit from the technology.
It is hoped it can eventually be rolled out to all patients.
The new technology means patients like Sian will not have to come into hospital every month for check-ups.
The device can be monitored remotely, which is particularly important during the pandemic.
