title: [Study of portable synchronous ECG recorder and its long-distance communication system].
abstract: This paper presents a convenient long-distance ECG communication system. It is made up of portable ECG recorder, hospital work station and public telephone network. This paper also introduces a kind of modulation and demodulation method in sound coupling communication-pulse edge modulation and demodulation. This system has rational structure, convenient operation and strong management power. A Philips 80C552 used as CPU in the recoder which is portable, cheap and reliable.
