It sounds like science fiction, but thankfully for many heart patients, it’s true!
A device called “Reveal LINQ“, which has been on the market in the U.S. since February, is produced by Medtronic. The device is basically heart-beat monitor, which has a three-year battery life, is one-third the size of an AAA battery. Its sensors and circuitry record every beat of the heart. The information is stored on a memory chip and transmitted wirelessly (YAY!!) to a patient’s doctor in the middle of the night for review later. The data are also analyzed by a computer programmed to look for erratic heart rhythms. Doctors can customize alerts, so if a patient’s heart rate gets to a certain level—too high or too low—the doctor gets an e-mail, page, or phone call.
