Abstract

Fetal condition may change abruptly during the pregnancy period. Therefore, continuous fetal electrocardiogram (FECG) monitoring will ease the fetal well-being. An algorithm has been developed to detect R-peak for the simultaneous measurement of the fetal and maternal heart rates during pregnancy. The algorithm is based on cross-correlation, adaptive threshold and statistical properties in the time domain. The performance achieved for the R-peak detection for the heart rate measurements shows that the model can extract R-peak for both maternal and fetal utilizing a single-lead configuration. The algorithm has been implemented into Altera's Stratix EP1S10. Test case results showed an error percentage of around ±0.3% and ±0.5% for the R-peak detection of maternal and fetal respectively. The system is capable to run at a maximum clock frequency of 48.56 MHz, and consumed 9 633 logic elements.
