The technology of real time telemetring and monitoring multi-channels ECGs through public telephone network

本文介绍的通过电话线实时遥测与监护多路心电信号的技术，在发射端先传输两个肢体导联的心电信号（Ⅰ、Ⅱ导联），接收端接收到后通过计算机计算得到另四个肢体导联的心电信号，所得的波形与用心电图机直接记录得到的一致，肢体导联信号（34秒）传输完毕，经自动导联切换再传输两路可选胸前导联（34秒）心电信号，监护中心将接收到的心电信号实时动态滚动显示，由心电数据库进行管理，供医生及时诊断与指导治疗，从而实现多路心电信号的实时遥测与监护。

In this essay a kind of technology of real time telemetring and monitoring multi channels ECGs through public telephohe network is presented. Two limb leaders (ⅠandⅡ ) ECG signals are transmitted from the sender at first.After they are received by the receiver the other four limb leadrs are calculated by computer in the basis of the reIation among the limb leaders, the received waveform and the calculated waveform are just the same as those described directly by Electro Cardiagragh. After the limb leaders ECG signals (34s) are transmitted, two selectable thorax leaders ECG signals are transmitted for 34 seconds after automatically changing the leaders. The received ECG waves are displayed on screen real time,shifting smoothly. After transmission doctors may make diagonoses and give some suggestion for treatment. Thus, telemetrying and monitoring multi channels ECGs is realized.
