ECG? There's an app for that!
People with heart disease will soon be able to provide vital information about their heart rhythm to their health care provider without making a visit to the doctor's office. In December, the FDA approved a mobile electrocardiogram (ECG) device that attaches to the back of an iPhone 4 or 5. To record an ECG, the user simply presses the fingers of both hands onto the electrode pads. The information is analyzed by an app, then transmitted digitally for storage on the company's website, where it can be accessed by a doctor.
