Prenatal Diagnosis of Atrioventricular Block and QT Interval Prolongation by Fetal Magnetocardiography in a Fetus with Trisomy 18 and SCN5A R1193Q Variant

Case Reports in Pediatrics, 2017
We report a case of fetal trisomy 18 with SCN5A R1193Q variant that presented with sinus bradycardia, 2 : 1 atrioventricular block (AVB), and QT interval prolongation.

Comparison of magnetocardiography and electrocardiography: a study of automatic measurement of dispersion of ventricular repolarization

, 2006
Aims There is some dispute over the clinical significance of dispersion of ventricular repolarization measurements from the electrocardiogram. Recent studies have indicated that multichannel magneto-cardiograms (MCGs), which non-invasively measure ...

Development of a highly balanced gradiometer for fetal magnetocardiography [PDF]

, 2008
Activation of the cardiac muscle is associated with ion transport through the membrane of the cardiac cell. This gives rise to the strongest electrophysiological signals in human body: the cardiograms.

Low Baseline Fetal Heart Rate Leads to Diagnosis of Long QT Syndrome Type 1

JACC: Case Reports
A low baseline fetal heart rate at 20 weeks’ gestation was detected in a fetus without cardiac structural anomalies. Fetal echocardiography and magnetocardiography were used to diagnose congenital long QT syndrome.

High-T-c SQUID gradiometer system for magnetocardiography in an unshielded environment

, 2006
We set up an electronic gradiometer for magnetocardiography (MCG) in an unshielded environment. The electronically balanced gradiometer consists of high-temperature radio-frequency superconducting quantum interference device (rf SQUID) magnetometers. The

Scanning High-T-C Squid Imaging System for Magnetocardiography

, 2009
A scanning magnetocardiography (MCG) system constructed from SQUID sensors offers potential to basic or clinical research in biomagnetism. In this work, we study a first order scanning electronic high-T-c (HTS) SQUID MCG system for biomagnetic signals ...

MgB2 SQUID for Magnetocardiography

, 2012
The discovery of the superconductivity at a transition temperature (TC) of 39 K in magnesium diboride (MgB2) has attracted much attention from many researchers for scientific as well as technical reasons [1]. Compared with Cu-based superconductors (cuprates), MgB2 has lower anisotropy and larger coherence length, in addition to high Tc [2].
