Portuguese microchip to fight heart disease

Scientists in Portugal believe they have created a device that could help the fight against a rare, and often fatal, heart condition.

Sudden cardiac death is particularly common among young sportsmen and women.

The scientists have developed a system that uses a microchip to examine a person’s genes for potential heart defects.

The medical community has given the microchip idea a cautious welcome, but stressed it is not a cure.
