The FDA is considering these new, expensive, wave of devices to remotely track those who have chronic diseases:

The device, known as a “hemodynamic monitor,” is designed to measure pressure inside the heart, along with body temperature and heart rate. The information is transmitted wirelessly via the Internet to a doctor’s office. There, medical personnel can tell, for example, if the patient is quickly building up fluids that could pool in the lungs, a potentially life-threatening situation. Depending on the patient’s condition and how hectic the doctor’s office is, the device could be set to send reports weekly, or even once or twice daily. The device doesn’t send alerts in an emergency, so the doctor must check the data on a regular basis.
