Noninvasive Fetal Electrocardiography: Models, Technologies and Algorithms [PDF]
In Innovative Technologies and Signal Processing in Perinatal
Medicine (pp. 99-146). Springer International Publishing (2020), 2021 The fetal electrocardiogram (fECG) was first recorded from the maternal abdominal surface in the early 1900s. During the past fifty years, the most advanced electronics technologies and signal processing algorithms have been used to convert noninvasive fetal electrocardiography into a reliable technology for fetal cardiac monitoring.

ECGAN: Self-supervised generative adversarial network for electrocardiography [PDF]
arXiv, 2023 High-quality synthetic data can support the development of effective predictive models for biomedical tasks, especially in rare diseases or when subject to compelling privacy constraints. These limitations, for instance, negatively impact open access to electrocardiography datasets about arrhythmias.

On uniqueness theorems for the inverse problem of Electrocardiography in the Sobolev spaces [PDF]
, 2021 We consider a mathematical model related to reconstruction of cardiac electrical activity from ECG measurements on the body surface. An application of recent developments in solving boundary value problems for elliptic and parabolic equations in Sobolev type spaces allows us to obtain uniqueness theorems for the model.

Labour Monitoring in Pregnant Women Using Phonocardiography, Electrocardiography and Electromyography Technique [PDF]
arXiv, 2023 Continuous monitoring of fetal and maternal vital signs, particularly during labor, can be critical for the child and mother's health. We present a novel wearable electronic system that measures, in real-time, maternal heart rate using phonocardiography (PCG) and Electrocardiography (ECG). Uterine contractions using electromyography (EMG).

Identification of weakly coupled multiphysics problems. Application to the inverse problem of electrocardiography [PDF]
Journal of Computational Physics, vol. 283, p. 271-298, 2015, 2015 This work addresses the inverse problem of electrocardiography from a new perspective, by combining electrical and mechanical measurements. Our strategy relies on the defini-tion of a model of the electromechanical contraction which is registered on ECG data but also on measured mechanical displacements of the heart tissue typically extracted from ...
