频域心电图是显示心电信号频域特征的一种无创伤性心电检测新技术。作者经204例正常图形分析,初步肯定了:图形容易辨认;正常范围明确,个体间变异不大;年龄、性别对图形有一定的影响,但对各函数图的影响不大;可重复性较好;仪器对描记条件的要求与普通心电图机相似。此外对心电信号频域分析的临床意义略加讨论。
Frequency domain electrocardiogram is a noninvasive ECG detection technology that shows the frequency domain characteristics of ECG. According to the analysis of 204 normal graphs, the author initially affirmed that the graph is easily recognizable; the normal range is clear and the variation among individuals is not significant; while the age and gender have some influence on the graph, but the effect on the graph is not significant; the repeatability Good; instrument requirements of the tracing conditions and ordinary ECG machine similar. In addition, the clinical significance of frequency domain analysis of ECG is slightly discussed.
