Abstract
A remote ECG monitoring and telemetry system for use in a hospital equipped with a master antenna television cable system comprising a portable patient sensor/transmitter unit for deriving ECG information and for transmitting a first frequency signal modulated with the ECG information; a receiver/transmitter unit positioned in the patient's room for receiving the first modulated signal and for coupling directly to the master antenna television cable a second frequency signal modulated with the ECG information; a converter/amplifier unit coupled to the master antenna television cable adjacent the head end thereof for receiving the second modulated signal and for coupling back into the master antenna television cable a high power, third frequency signal modulated with the ECG information; and a receiver/demodulator unit coupled to the master antenna television cable at a central monitoring station for receiving and demodulating the third modulated signal to derive the ECG information.
