Efficient fetal-maternal ECG signal separation from two channel maternal abdominal ECG via diffusion-based channel selection
This addresses the need for affordable and widely deployable monitors to improve maternal and fetal health during pregnancy and delivery.
The paper tackled the problem of separating maternal and fetal ECG signals from a two-channel abdominal recording, presenting an algorithm based on diffusion-based channel selection that achieved accurate separation with clinical validation.
There is a need for affordable, widely deployable maternal-fetal ECG monitors to improve maternal and fetal health during pregnancy and delivery. Based on the diffusion-based channel selection, here we present the mathematical formalism and clinical validation of an algorithm capable of accurate separation of maternal and fetal ECG from a two channel signal acquired over maternal abdomen.
