Magnetocardiography: Ventricular arrhythmias

European Heart Journal, 1993
Since 1985, magnetocardiographic (MCG) mapping has been carried out in patients with severe ventricular arrhythmias, related to primary cardiomyopathy and ischaemic heart disease, for the purpose of non-invasive localization of the arrhythmogenic substrate or to screen patients at risk of sudden death. Data reported by several authors have demonstrated

Magnetocardiography and exercise testing

Journal of Electrocardiology, 1994
Twenty healthy male subjects (age range, 15-25 years; median, 21 years) underwent magnetocardiography during physical exercise. Significant ST-segment displacements of the magnetic signal were found during exercise at a heart rate of 120 beats/min compared to the magnetic signal at rest (P < .001).

Recent advances in magnetocardiography

Journal of Electrocardiology, 2004
New developments in instrumentation, in clinical application, as well as in data analysis and visualization have provided new momentum to magnetocardiography (MCG). On one hand robust, easy to use and budget-priced MCG-systems entered the market and are applied to a multi-centred clinical study. On the other hand highly sophisticated vectormagnetometer

Magnetocardiography: An Overview

IEEE Transactions on Biomedical Engineering, 1979
Since 1963 when recording of the human magnetocardiogram (MCG) was first reported, the number of clinical studies has been limited. High-quality tracings can now be easily obtained in special shielded chambers, but problems remain if records are to be made in hospitals without such chambers.

Clinical value of magnetocardiography

1989
Magnetocardiography, 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].

Monitoring fetal development with magnetocardiography

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
Fetal 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.

Magnetocardiography and cardiac risk

Herzschrittmachertherapie und Elektrophysiologie, 1997
Risk 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

1996
As 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 ...
