The Queesland University of Technology in Brisbane, Australia has combined a mobile phone with a miniature heart monitor and a GPS device in research aimed at tackling the low participation rates of heart patients in cardiac rehabilitation. The unique 'Cardiomobile' monitoring system, developed by Gold Coast company Alive Technologies, is being further developed and under trial together with the University under an ARC Linkage Grant.

Dr. Charles Worringham of Queensland University of Technology's Institute of Health and Biomedical Innovation stated, "The program allows people who have been in hospital for a heart attack or heart surgery to undergo a six-week walking exercise rehabilitation program wherever it's convenient, while having their heart signal, location and speed monitored in real time."

Dr. Worringham went on to say that the program was initiating the Cardiomobile approach because 80 per cent of cardiac patients do not complete recommended hospital outpatient rehabilitation programs, despite the reduced risk of recurrent heart attacks, death and re-hospitalization, and improvement both function and quality of life. "It's not because they don't want to take part, it's usually because they cannot get to the hospital's program easily, because there simply isn't one nearby, or because work or family commitments take priority."
Dr. Worringham said country singer and songwriter Alan McPherson was one of the first to trial the system, and that the singer was able to do rehabilitation sessions under proper monitoring while on tour. "Without the system he would have either had to cancel his tour, forgo the rehab program, or take a chance and exercise with no monitoring or support."

The Cardiomobile system works by the patient attaching to their chests a mini ECG (electrocardiogram or heart signal) monitor and wearing a cap with a lightweight GPS receiver, both connected to a mobile phone via Bluetooth.

"Patients phone in at the start of their scheduled session and then their heart signal, location, speed and gradient are monitored in real-time over the web by a qualified exercise scientist, who guides the patient's program and checks their progress," Dr. Worringham said.

"If there is any problem with the heart signal we can immediately contact the patient, and consult with the cardiologist if needed.

"Although serious problems in cardiac rehab are very rare, if there is an emergency we can direct the paramedics to the exact location without delay. While this approach is different from a hospital-based program, we are talking about a group of patients who either wouldn't exercise at all or would have to go it alone - something many lack the confidence for after heart attacks and surgery."

"If this approach works, it could go a long way towards assisting the recovery of heart patients not reached by conventional rehabilitation, and help to cut the number of avoidable re-admissions to hospital," Dr. Worringham said.
