Clinical value of magnetocardiography
1989Magnetocardiography, that is to say the recording of the magnetic field generated by the electrical activity of the heart, was born in 1963 when Baule and McFee, using an induction coil, measured for the first time magnetic signals produced by a human heart [2].

Magnetocardiography and cardiac risk
Herzschrittmachertherapie und Elektrophysiologie, 1997Risk evaluation is a challenging problem in clinical cardiology. Recently, the development of new therapeutic strategies for malignant cardiac arrhythmias and ischemia has urged the need for more accurate screening methods of risk patients The purpose of this review is to summarize the current scientific evidence on the applicability of a new method ...

Magnetocardiography, an introduction
1996As introduction to magnetocardiography, first a general view of the cardiovascular system is given with special emphasis on the anatomy and physiology of the heart. A short overview of the pathophysiology of the heart so far relevant for the understanding of the possiЫe applications of magnetocardiography is followed by an historical survey of the ...

Monitoring fetal development with magnetocardiography
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005Fetal heart rate variability (fHRV) is useful for noninvasive assessment of the status of the autonomic nervous system of the developing fetus. In this pilot study we acquired fetal magnetocardiograms (fMCG) in a magnetically shielded environment.

A realistic torso model for magnetocardiography
The International Journal of Cardiac Imaging, 1991This paper contains the description of an inhomogeneous, multi-compartmental volume conductor model which is in use in our group. Although initially developed for the study of the ECG, it has been found to serve equally well for simulating the magnetocardiogram (MCG), the forward problem, and as a basis for source analysis of the MCG, the inverse ...

Standardization of magnetocardiography in nonhuman primates
Physics in Medicine and Biology, 2008To establish the electrophysiological mappings of nonhuman primates by using magnetocardiogram (MCG) data and obtain the normal values of MCG parameters, we used 64-channel superconducting quantum interference devices to measure 8x8 MCG data for 95 cynomolgus monkeys (Macaca fascicularis, 51 female and 44 male).

Solving the inverse problem in magnetocardiography
IEEE Engineering in Medicine and Biology Magazine, 1994Biomagnetic methods have proven to be valuable as research tools in obtaining functional information that is difficult to gain by conventional clinical imaging methods. Still, the magnetocardiographic localization method has to compete with corresponding bioelectric measurements and other noninvasive methods, such as two-dimensional echocardiography ...
