冠状动脉支架植入术是冠心病血运重建的有效方法之一。为了解其对心电频谱的影响,我们采用心电频谱分析方法,评价了支架植入术前后心脏自主神经功能的改变。心电频谱是通过对电信号的频域分析,可将普通心电图信号的时域信息变换为频域信息,进行多参数、多指标和相关动态的综合 Coronary stent implantation is an effective method of revascularization of coronary heart disease. To understand its impact on the ECG spectrum, we used electrocardiographic analysis to assess changes in cardiac autonomic function before and after stent implantation. ECG spectrum is the frequency domain analysis of electrical signals, the ordinary ECG signal can be transformed into time-domain information in the frequency domain information, multi-parameter, multiple indicators and related dynamic synthesis
