Wireless Heart MonitorUniversity of Ulster researchers have developed a wireless cardiac monitoring device that allows patients at high risk of cardiac arrest—those who traditionally would be monitored by in-hospital instruments—to wirelessly monitor their hearts with a tiny electrocardiogram. It doesn't say exactly what technology they're using to communicate with the hospitals (hopefully something with a good range or you'll start seeing a lot more patients with Pringles cans on their canes), but any extra warning that can be given of heart arrhythmia can help, even if it's just a few minutes.

Of course, from the picture, it might help if the weak-hearted (Northern) Irish would take a break from the disco floor once in a while.
