If you find yourself urgently needing to perform an ECG (electro-cardiogram) outdoors in rain or snow, then Casio has just the device.

The company exhibited a ruggedised Cassiopeia EG-800 PDA (personal digital assistant) connected to an ECG heart monitoring machine at the Networks Telecom tradeshow in Birmingham this week.

The monitor is operated via ECG software from Dutch company Cardio Control, which runs on the PDA’s operating system, Microsoft’s Pocket PC.

"The software can be installed in any of our devices, but it is most suitable on the EG-800," said Amanda Recknell, product manager at Casio. The company is aiming the device at hospitals and paramedics who need a mobile system.

The ruggedised PDA can survive a fall from a height of 75cm, and can be used in heavy rain or other tough weather conditions, according to Casio.

The EG-800 with the ECG software will be available in the UK from 17 July, and costs £2,000.
