An ECG telemetry system for physiological studies on swimmers.
A low frequency telemetry system is described which has been designed to allow high quality ECG measurements to be made on active swimmers. The transmitting antenna is a small loop worn by the swimmer whilst the receiver is fed from a single wire loop around the swimming pool. Both ECG electrodes and the transmitter case are made in a waterproof form which allows the swimmer complete freedom of action to dive and swim normally. The transmitter can be constructed from normal miniature components although the present version has been assembled using thick film techniques which combine high reliability with a reduction in overall volume.
