Abstract

This paper describes a method for locating QRS complex in noninvasive FECG, using techniques based on MECG cancellation, and Principal Component Analysis. We use a database composed of 15 maternal abdominal electrocardiograms, 4 leads each, sampled at 1000 Hz. The database contains reference annotations that mark the actual locations of each fetal QRS complex. The position of each QRS complex is compared with the estimated position of each actual QRS complex to determine the performance of the proposed method. The proposed method locates the fetal QRS complexes with efficiency above 80% in databases highly contained with noise uterine and fetal movement.
无创胎儿心电图中胎儿心率的估计
本文介绍了一种在无创FECG中定位QRS复合物的方法,该方法采用基于MECG抵消和主成分分析的技术。我们使用一个由15个产妇腹部心电图组成的数据库,每个心电图有4个导联,采样频率为1000hz。该数据库包含标记每个胎儿QRS复合体实际位置的参考注释。将每个QRS复合物的位置与每个实际QRS复合物的估计位置进行比较,以确定所提出方法的性能。该方法在高度含噪声子宫和胎动的数据库中定位胎儿QRS复合物,定位效率在80%以上。
