Mini ECG to Help Monitor Heart Attack Rehab Patients

Scientists at Queensland University of Technology's Institute of Health and Biomedical Innovation have developed a unique 'Cardiomobile' monitoring system that acts as a mini ECG, helping heart attack rehab patients to keep a check on their heart signal at any time and place.

Dr Charles Worringham said that the system developed by Gold Coast company Alive Technologies, was being further developed and put on trial together with QUT under an ARC Linkage Grant.

Heart Attack - Overview
Heart attack is the death of the heart muscle due to loss of blood supply. Heart disease is the leading cause of death in the United States. Other names for heart attack include acute myocardial infarction, coronary thrombosis, and coronary occlusion.

"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," said Dr Worringham.

He added: "We are trying this approach because 80 per cent of cardiac patients never complete recommended hospital outpatient rehabilitation programs, despite the fact that they cut recurrent heart attacks by 17%, substantially reduce deaths, prevent re-hospitalisation, and improve 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."

Angioplasty
Arteries supplying the heart is sometimes blocked by plaque leading to heart attack.Angioplasty is a method by which a part of the blocked artery is expanded to place a stent.Once this is done normal blood flow resumes and the heart regains its normal function.

He also said that country singer and songwriter Alan McPherson was one of the first to trial the system.

"Mr McPherson was able to do his rehabilitation sessions while on tour from Queensland to Victoria knowing he was being properly monitored. Without the system he would have either had to cancel his tour, forego the rehab program, or take a chance and exercise with no monitoring or support," he said.

Coronary Artery Bypass Grafting (CABG) | Coronary Artery Bypass Surgery
Coronary artery bypass grafting (CABG) or heart bypass surgery is an open heart surgery to relieve the blockages of the arteries of the heart. Coronary artery bypass surgery lasts up to 3 to 6 hours.

This 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," said Worringham.

He added: "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."
