Artefacts can pose a big problem in the analysis of electrocardiogram (ECG) signals. Even though methods exist to reduce the influence of these contaminants, they are not always robust. In this work a new algorithm based on easy-to-implement tools such as autocorrelation functions, graph theory and percentile analysis is proposed. This new methodology successfully detects corrupted segments in the signal, and it can be applied to real-life problems such as for example to sleep apnea classification.
伪迹在心电图(ECG)信号分析中可能会造成很大问题。尽管存在一些方法来降低这些干扰因素的影响,但它们并不总是稳健的。在这项工作中,提出了一种基于易于实现的工具(如自相关函数、图论和百分位数分析)的新算法。这种新方法成功地检测出信号中损坏的部分,并且可以应用于实际问题,例如睡眠呼吸暂停分类。
