The effect of maternal pregestational diabetes on fetal autonomic nervous system

Physiological Reports, 2023
Heart rate variability assessment of neonates of pregestational diabetic mothers have shown alterations in the autonomic nervous system (ANS). The objective was to study the effect of maternal pregestational diabetes on ANS at the fetal stage by ...

A movable unshielded magnetocardiography system

Science Advances, 2023
Magnetocardiography (MCG), which uses high-sensitivity magnetometers to record magnetic field signals generated by electrical activity in the heart, is a noninvasive method for evaluating heart diseases such as arrhythmia and ischemia. The MCG measurements usually require the participant keeping still in a magnetically shielded room due to the ...

Optical Magnetometer Employing Adaptive Noise Cancellation for Unshielded Magnetocardiography [PDF]

, 2013
This paper demonstrates the concept of an optical magnetometer for magnetocardiography. The magnetometer employs a standard Least-Mean-Squares (LMS) algorithm for heart magnetic field measurement within unshielded environment.

A method for noninvasive beat‐by‐beat visualization of His bundle signals

Annals of Noninvasive Electrocardiology, 2023
Background Invasive recording of His bundle signals (HBS) in electrophysiological study (EPS) is important in determining HV interval, the time taken to activate the ventricles from the His bundle. Noninvasive surface measurements of HBS are attempted by

Magnetization Dynamics Control for Noise Reduction in Fluxgate Sensors

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Fluxgate sensors are indispensable for the detection of weak magnetic fields. However, their noise performance remains constrained by an incomplete understanding of the interplay between the high‐frequency magnetization dynamics of the core material and the overall sensor behavior.

Electrophysiological characterization of pre‐adolescents born with intrauterine growth restriction: insights from clinical and computational data

The Journal of Physiology, Volume 604, Issue 13, Page 5276-5295, 1 July 2026.
Abstract figure legend Depolarization and repolarization duration analysis was conducted in preadolescent groups with IUGR and controls using a 12‐lead ECG. Principal component analysis was applied over the 12‐lead ECGs to generate spatially transformed leads better suited for robust ECG fiducial points detection.

Heart Rate Variability in Newborns From Diabetic Mothers: Clinical Application and Significance

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
Risk factors for GDM contribute to a hyperglycemic intrauterine environment, which may in turn impair ANS function in the offspring. Altered ANS activity can be assessed through measures such as HRV. ABSTRACT Gestational diabetes mellitus (GDM) is one of the most common pregnancy complications, arising from inadequate insulin secretion and increased ...
