been around, but a new option is about to surface for AT&T customers. The service, which will be offered up starting April 21st by MedNet Healthcare Technologies, will somehow let patients monitor their own heartbeats and automatically send that information to their cardiologists using Bluetooth-enabled phones. Reportedly, the information will be sent out to a central monitoring center, which then transfers the data to the doctor. As expected, there will be a monthly fee for the service (exact pricing has yet to be disclosed), and doctors must also be signed on to receive the information. Sounds good and all, but seriously, good luck getting your M.D. to be attentive to your every data dump.
