An improved technique for automatic monitoring and analysis of ECG recording is described. The system is based on standard commercial equipment but provides improved quantitative measurement of cardiac arrhythmias. This is done by using a simultaneous recording of a 100 Hz clock, which is used to correct for tape speed variations. Also increased immunity to artefacts is achieved by combining two ECG leads, coupled with signal analysis techniques. The problems arising from certain types of artefact are also discussed.
本文描述了一种用于自动监测和分析心电图记录的改进技术。该系统基于标准商业设备，但能对心律失常进行改进的定量测量。这是通过同时记录一个100赫兹的时钟来实现的，该时钟用于校正磁带速度变化。此外，通过结合两个心电图导联以及信号分析技术，还提高了对伪迹的抗干扰能力。文中还讨论了某些类型伪迹所产生的问题。
