Abstract
The invention is a telemetric biomedical system for simultaneously transmitting a pacer pulse together with lower frequency ECG wave forms and a loose lead signal. The loose lead signal is a low frequency signal applied across the skin electrodes which are attached to a patient subject to cardiac monitoring. In the event that such electrodes should become detached or poorly coupled to the patient, the loose lead signal tends to become open circuited across the leads and can be detected. The loose lead signal and ECG wave form since from the patient, is transmitted in an FM/FM modulated signal, while the pacer pulse is separated from the ECG wave form prior to amplification and is simultaneously transmitted as an FM modulated signal. In addition thereto, various alarm signals are transmitted as FM modulated signals with the pacer pulse.
