Bedside Magnetocardiography with a Scalar Sensor Array

Sensors
Decades of research have shown that magnetocardiography (MCG) has the potential to improve cardiac care decisions. However, sensor and system limitations have prevented its widespread adoption in clinical practice. We report an MCG system built around an

Clinical implications of fetal magnetocardiography [PDF]

Ultrasound in Obstetrics & Gynecology, 2002
AbstractObjectivesTo test the usefulness and reliability of fetal magnetocardiography as a diagnostic or screening tool, both for fetuses with arrhythmias as well as for fetuses with a congenital heart defect.MethodsWe describe 21 women with either a fetal arrhythmia or a congenital heart defect discovered during prenatal evaluation by sonography. Four

Millimetre-scale magnetocardiography of living rats with thoracotomy

Communications Physics, 2022
Causes of heart failure can be investigated by tracing imperfections in electrical current propagation on the millimetre scale; however, the spatial resolution of current magnetocardiograph methods are limited to the centimetre-scale.

Magnetocardiography in Early Detection of Electromagnetic Abnormality in Ischemic Heart Disease [PDF]

Journal of Arrhythmia, 2008
Ischemic heart disease (IHD) is one of the leading causes of death in the general population. Ischemia induces changes in the electrophysiologic properties of the myocardium that sometimes cannot be detected with rest ECG, which has a relatively low ...
