Atrioventricular conduction abnormalities are associated with poor outcome following intermittent umbilical cord occlusions in fetal sheep

Acta Obstetricia et Gynecologica Scandinavica, Volume 104, Issue 6, Page 1207-1217, June 2025.
Continuous electrocardiographic monitoring of fetal sheep heart during intermittent umbilical cord occlusions gradually leading to severe metabolic acidemia revealed several fetal arrhythmias including atrioventricular block, ventricular tachycardia, and ventricular fibrillation that would have gone unnoticed with current fetal monitoring systems ...

Electrocardiographic imaging metrics to predict the risk of arrhythmia in patients with ischemic cardiomyopathy

Journal of Arrhythmia, Volume 41, Issue 1, February 2025.
ECGi‐specific studies for assessment of arrhythmic risk in ischemic heart disease. Studies specifically using ECGi have identified several metrics that may be associated with ventricular arrhythmia risk in patients with ischemic cardiomyopathy. ARI, activation‐recovery interval; AT, activation time; ICM, ischemic cardiomyopathy; LV, left ventricle; MI,

Rotary excitation of non‐sinusoidal pulsed magnetic fields: Towards non‐invasive direct detection of cardiac conduction

Magnetic Resonance in Medicine, Volume 92, Issue 5, Page 1965-1979, November 2024.
Abstract Purpose There is a need for high resolution non‐invasive imaging methods of physiologic magnetic fields. The purpose of this work is to develop a MRI detection approach for non‐sinusoidal magnetic fields based on the rotary excitation (REX) mechanism which was previously successfully applied for the detection of oscillating magnetic fields in ...

Ultra‐compact and high‐precision differential detection method based on liquid crystal polarization grating for miniature atomic magnetometer

Nanophotonics, Volume 13, Issue 23, Page 4255-4265, November 2024.
Abstract Atomic magnetometers (AMs) that use alkali vapors, such as rubidium, are among the most sensitive sensors for magnetic field measurement. They commonly use polarization differential detection to mitigate common‐mode noise. Nevertheless, traditional differential detection optics, including polarization beam splitters (PBS) and half‐wave plates,
