ECG Data Compression: Some Practical Considerations
J. C. M. Peden · 1982
In computer assisted reporting of electrocardiograms, it is necessary to store and transmit relatively large volumes of data. ECG signals recorded at the body surface are amplified and A/D converted at a rate of 500 samples per second. In a system presently under development at Glasgow Royal Infirmary, 10 body surface signals are simultaneously measured for 8 seconds. With an A/D resolution of 5 µV per bit, this provides 4.8 × 10 5 bits of information.
