Attorney, Agent, or Firm—Gunn & Associates, P.C. [57] ABSTRACT
Amedical lacility alter discharge ol a cardiovascular patient, can remain in contact with the patient. The patient is provided with a multiple lead EKG terminal spread placed on the body, and the signals therefrom are collected and transmitted. They are transmitted to a remote central location. At the central location, the transmitted EKG data is analyzed. It is compared with normal EKG signals and signals captured in time from the same patient as part ol the patient history. The evaluation is done through a neural network which forms an output signal automatically or through intervention ol a cardiologist sending an alarm condition signal to the patient instructing the patient to get immediate treatment at the patient's location or to otherwise go to a specific medical lacility. Signal preparation includes providing EKG signals through a multiplexer, conversation into a digital data, removal ol bias signals, stabilization ol this EKG base line, compression and data transmission through a modulator. The receive signal is reconstructed to provide an EKG signal ol the patient which is then evaluated in the neural network. As appropriate, transmitter/receiver repeater stations and synchronous satellites are used to convey these signals.
