CardioFlux represents a next-gen evolution of
magnetocardiography (MCG); its use of optically pumped magnetometers (OPM) eliminates the need for liquid helium cooling, previously an obstacle to widescale commercial adoption of MCG.
A potential near-future application of such systems is a low-cost
magnetocardiography (MCG) system using MR sensors [5].
With currently available diagnostic tools, fetal ultrasound cardiography, and fetal
magnetocardiography, most of CHB could be successfully diagnosed and comprehensively evaluated prenatally.
Fetal
magnetocardiography (fMCG) using superconducting quantum interference device allows accurate assessment of beat-to-beat fetal heart rate variability [2].
Indeed, if one could image action currents using MRI, it would be a fundamental advance that might make
magnetocardiography and even much of electrocardiography obsolete.
Further details such as QT interval prolongation and functional AVB due to prolonged ventricular repolarization were accurately diagnosed by fetal
magnetocardiography (fMCG).
Fetal
magnetocardiography (fMCG) is a noninvasive test that acquires the electrical activity of the fetal heart over the maternal abdomen (1).

This kind of magnetometer is vastly used in
magnetocardiography, and it can reach sensitivity of 99 fT/[Hz.sup.1/2] [7].
