Scientists are examining whether genetic engineering could help heart disease patients redevelop damaged heart cells and replace the need for pacemakers.
A pacemaker is a battery-powered device for slow or irregular heart beats, usually caused by heart cell degeneration in old age. Without such a device, a slow heart beat could lead to weakness, confusion, dizziness, fainting, shortness of breath and death.
``If the heart stopped for more than two seconds, the patient may faint and, in the worst case, die suddenly,'' Hong Kong University cardiology professor Lau Chu-pak said on Monday.
