The implant that alerts you before a heart attack (USA)

Heart disease kills more than 2,200 Americans every day, but an innovative new warning system could help reduce that number substantially. A new device that acts as an early warning system aims to curb the number of heart attack deaths in older adults. The AngelMed Guardian implant, which is featured in an upcoming issue of the journal Ergonomics in Design, could potentially save thousands of lives a year. But how does the high tech warning system work? The device is surgically implanted under the skin like a pacemaker or defibrillator. Once it's in place, the AngelMed guardian alerts the patient to an oncoming attack with vibrations, audible tones, and flashing warning lights beamed to an external, pager-like device. There are two alarm levels: Low-priority and high-priority. A low-priority warning signals that something might be wrong, so the patient should visit a doctor within 48 hours. The high-priority alarm goes off when a patient is having a heart attack
