AliveCor's iPhoneECG case was pretty sweet but, being a case, could only be strapped to an iPhone 4. Doctors content with their 3GS or patients who prefer to hug an iPad to their chest will be elated to hear the company is working on a more hardware-agnostic option for your iOS heart monitoring needs. The business card-sized iCard ECG mounts to the back of your iDevice using velcro and wirelessly feeds data from its electrodes to the AliveECG app. The app automatically records 30 seconds of your heart's rhythmic pulse before uploading it to AliveCor's servers for sharing with your doctors. The bad news? They're still awaiting FDA approval, so you can't run out and pick one up just yet. But, when it does hit shelves, it looks like you'll have a choice of red or black -- so you can make sure your medical accessories match your scrubs. Check out the video after the break.
