Abstract
Fetal Heart Rate (fHR) monitoring and derivation of the fetal electrocardiogram (fECG) are important in assessing fetal distress during pregnancy and delivery. Currently used methods of obtaining the fECG using an invasive scalp electrode are however not suited for long term observation throughout the pregnancy due to their invasiveness. A recently published method enables monitoring of the fHR and fECG non-invasively using abdominal contact electrodes [1]. The method removes the maternal ECG (mECG) to increase the SNR implementing the following steps: preprocessing, maternal R-peak detection, mECG estimation, and mECG subtraction. Due to its complexity however, the method proposed in [1] is unsuitable for continuous ambulatory use. In order to reduce the algorithms’ complexity, the maternal R-peak detection step is replaced [2]. A new R-peak detection algorithm based on the Discrete-Time Continuous Wavelet Transform (DT-CWT) is proposed as a first step in reducing the overall computational complexity of [1], while increasing detection quality of the maternal R-peak detection.
