Surgeons in Adelaide have pulled off a nationwide-first – attaching a miniature heart monitor to wirelessly diagnose and manage irregular beats.

The tiny device weighs less than three grams and is miniscule compared to previous iterations. It allows information about a patient's heart to be recorded and sent to medical staff without the patient ever having to leave home.

Just three different institutions around the world have used the device, only made available this year.

Professor of Cardiology Research at the RAH and University of Adelaide, Prash Sanders, says he hopes the device will be widely available as soon as possible.

“This is I think a device that's going to change our therapy as we move into the future and change our approach to young patients and also that group of patients who are at risk of having a stroke and we can make a real difference with this.”
