AliveCor has added to the iPhone's many uses by making it a crucial part of the company's new mobile heart monitor, which now has both 510(k) clearance and CE mark conformity. Presale to medical professionals begins immediately, and European sales begin in early 2013. AliveCor's device design is simple, placing electrodes into a case that snaps on the back of Apple's iPhone 4 and 4S models. A patient can obtain an electrocardiogram (ECG) by holding the device while relaxed and pressing fingers from each hand onto two of the electrodes, or just by placing the device on the chest. Rhythm strips can be of any duration, and the iPhone and secure cloud storage houses the data for subsequent analysis, sharing and printing. Release
