  • Title: A biotelemetry system for monitoring heart rates in unrestrained ungulates.
    Author: Johnston RH, MacArthur RA, Geist V.
    Journal: Biotelem Patient Monit; 1980; 7(3-4):188-98. PubMed ID: 7213953.
    Abstract:
    An EKG telemetry system has been designed for use on free-living ungulates. An FM transmitter with a battery life of 2 +/-0.5 months and a range of 2-6 km is mounted on the back of the animal by means of an adjustable harness. The EKG signal is detected by subdermal electrodes overlying the sternum and transmitted to an FM receiver equipped with a frequency down-converter. The output of the receiver is the modulated audio carrier which is recorded on magnetic tape. The EKG waveform is recovered from the tape-recorded signal using an FM demodulator connected to a strip chart recorder.
