Traditionally, doctors would have implanted a loop recorder the size of a USB stick into a patient's chest to monitor their heart rate.
If the patient experienced a blackout they would then use a separate device to freeze the recording which could then be assessed by a consultant at the hospital.
The new monitor offers all the same benefits, but is a tenth of the size of the traditional loop recorder, making it much more comfortable and less noticable under the skin - it is nearly invisible to the naked eye in most patients.
It also comes complete with its own implant kit which means there's no need for surgical kit and scalpels, and only requires an incision of less than 1cm.
It is hoped that in the future the procedure will be performed in only ten minutes in a treatment room, rather than in a theatre setting.
Dr Linker said: "From my perspective it was amuch simpler and quicker procedure, and it was very easy to do."
