心电图波形的振幅及形态等对临床心电图诊断至关重要。为了使波形降低噪声,心电图机都内配有抗干扰滤波器,相关人员应该了解滤波器滤波功能使用指征及其对心电图波形的抑制与致畸作用,不仅要正确设置检定时心电图机滤波器,还应该知道这样设置的原因。本文主要介绍心电图机输出信号 The amplitude and shape of the ECG waveform are crucial for clinical ECG diagnosis. In order to reduce the noise waveform, ECG machines are equipped with anti-interference filter, the relevant personnel should understand the use of filter filtering indications and ECG waveform inhibition and teratogenic effects, not only to set the correct electrocardiograph filter, You should also know the reason for this setting. This article introduces the ECG output signal
