Quote Australian newspaper the Herald and Sun.
''MELBOURNE doctors are carrying out a world-first study to try to defuse the “ticking time bomb” of the most common heart rhythm disorder.
Their world-first study of the role of a gene in predisposing people to atrial fibrillation aims to detect or even predict the condition’s occurrence.
Those whose condition is undetected are unwittingly at risk of heart attack and stroke.
The Royal Melbourne Hospital’s director of cardiac electrophysiology, Professor Jon Kalman, said the condition was linked to high blood pressure, heart disease, thyroid problems and obesity.
But in many patients its cause was unknown.''
