Pacemaker Malfunction With Radiotelemetry
JAMA: The Journal of the American Medical Association, 1971To the Editor.— Electrical and radiofrequency devices have long been known to interfere with cardiac pacing and as such have represented potential hazards. 1,2 Lichter et al 3 reported two patients who had ventricular fibrillation when electric cautery was used to open the pericardium.

Radiotelemetry of avian electrocardiogram
Medical & Biological Engineering & Computing, 1980A radiotelemetry system has been developed which is capable of transmitting electrocardiogram signals from domestic fowl. The transmitter circuit consists of a frequency-modulated Colpitts oscillator operating at 104·5 MHz, followed by a single-ended amplifier. The devices are fabricated as thin-film hybrid microcircuits. Transmitters were encapsulated

Non-invasive fetal monitoring using radiotelemetry
Clinical Physics and Physiological Measurement, 1983A telemetry system for non-invasive monitoring of fetal heart rate and uterine contractions is described. Fetal heart information is obtained by means of Doppler ultrasound, and contractions information using an external tocodynamometer. The more important features of the device are described in detail; the full design is available from the authors ...

Combined telephone and radiotelemetry of the EEG
Electroencephalography and Clinical Neurophysiology, 1969Abstract Multichannel local radiotelemetry of the EEG has been combined with onward transmission of the EEG data by telephone as frequency modulated audio subcarriers from the radio receiver located in the subject's house. Records are presented from a normal 10-year-old child, and are free from major artifacts. On-line spectral analysis was performed,

Movement patterns and radiotelemetry
2009Abstract There is no greater need for details on the year-round movements and refuges of amphibians in their natural habitats than today, mainly due to the pressure to develop lands for human habitation, agriculture, and commerce, and to define better wetland/buffer zones to protect amphibian communities. Unfortunately, there is a dearth

A portable radiotelemetry receiver for ambulatory monitoring
Journal of Biomedical Engineering, 1982Abstract Since the idea of small radiotelemetry capsules was introduced some twenty year ago, improvements have been made to the transmitters but little attention has been paid to the receiver/decoder system. The size of the conventional system makes ambulatory measurements difficult: the use of multiple aerial systems increases this difficulty ...
