高通滤波电路对心电波形ST段精确测量的影响研究

The Effect of High-pass Filter Circuit on Accurate Measurement of ST-segment

在心电图测量中,高通滤波是为了克服极化电压而设计的。高通滤波会影响心电ST段测量的准确性,而ST段测量的准确性将影响相关心脏疾病的诊断与治疗评价。该文利用心电检测平台分别在不同的高通滤波频率下测试对ST段的影响,并通过研究高通滤波对心电ST段测量的影响,从而正确地使用不同的应用模式。

The high-pass filter which is designed to overcome the polarization voltage in the ECG measurements can affect the measurement of the ST-segment; but the accuracy of the ST-segment will have an impact or1 the diagnosis and treatment of heart diseases. This paper used the ECG detection platform to test the effect of the high-pass filter at different frequency and studied the effect of the high-pass filter on the ST segment to ensure proper use of different application modes.
