A simple, PC-dedicated, implanted digital PIM radiotelemetric system.

ABSTRACT

The short-distance, PC-dedicated implanted telemetry system is described. Schematic drawings of the transmitter and Centronics port interface are given and the main problems of the controlling program are discussed. The interface can be easily converted to serve as an analog output and the method of adaptation is demonstrated. The whole system was tested in animal experiments with two different amplifiers and the examples of resulting direct ECG and both direct and integrated intestinal EMG recordings are included.
