Seattle-based AliveCor is unveiling a wireless casing for the iPhone 4 called the iPhone ECG that, combined with an accompanying app, turns the device into a hospital-quality electro-cardiogram measuring instrument (ECG) at the Consumer Electronics Show later this week. The unit, which is expected to sell for around $100, can be used to monitor heart conditions and pacemakers, alert users of atrial fibrillation and print or email the results as a PDF file.
