摘　　要：介绍了心电图机产生50Hz交流干扰的各种原因,采用电路分析的基本方法,从理论上推导出广泛使用的心电图机ECG6511抑制50Hz交流干扰滤波器的工作原理。The paper introduces all kinds of causes bringing about 50 Hz alternating current interferences. At the same time, deriving the operational principle of the filter, which is a part of the widely used ECG6511, from the basic methods of circuit analyses and hoping helpful to persons of the same occupation when they analyze and repair other filters in medical instruments and equipment.
