Turn Your iPhone into a Medical Device

I'm amazed by the simplicity of the device. No base-station, or unwieldy dongle or cables - just a fairly innocuous looking case that just happens to have a couple electrodes on the surface.

Pretty cool!

iPhone ECG System Does Your ECG & Monitors Heart Rate, Can Stream Reports Wirelessly!:

The ECG Case physically appears like just another iPhone case except that a couple of shiny electrodes are stylishly inscribed on its back. Users can slip in the iPhone into this case and launch the corresponding application to use the iPhone - 

1. For ECG
2. Heart Rate Trend Monitor 

The iPhone ECG app, once launched turns your iPhone into “wireless clinical quality cardiac equipment” that can record your ECG. It allows you to store this data locally on your iPhone or wireless stream it to your doctor or other connected devices.
