ECG lead mode selecting, multi channel A/D, and analogcardiac electric signal processing are implemented. Run length DSGM detection ispresented. Feature detection and diagnosis are achieved with ECG steady periodicstructure feature. Efficiency synchronous spectrum compression is studied. Higher compression ratio is acquired with high fidelity. Multi channel ECG supervision, control, and processing PC system is constituted with PC and sampling and processing units. The system have perfect functions, such as multi channel real time supervising, fast detection and diagnosing, effective compressing with highfidelity, and expansible tele recalling and tele diagnosing.
