Clinical application of magnetocardiography

Expert Review of Molecular Diagnostics, 2005
Magnetocardiography is a noninvasive contactless method to measure the magnetic field generated by the same ionic currents that create the electrocardiogram. The time course of magnetocardiographic and electrocardiographic signals are similar. However, compared with surface potential recordings, multichannel magnetocardiographic mapping (MMCG) is a ...

Recommended Standards for Fetal Magnetocardiography [PDF]

PACE - Pacing and Clinical Electrophysiology, 2003
Fetal magnetocardiography (FMCG) is increasingly being used in research and diagnostics of fetal heart function. Currently, FMCG is the only noninvasive procedure available, comparable to postnatal ECG, which can be used to assess cardiac electrophysiology during the second and third trimester of pregnancy.

Fetal Magnetocardiography [PDF]

Rinsho byori. The Japanese journal of clinical pathology, 2006
Fetal magnetocardiography is a non-invasive method to study the fetal heart: the patient (i.e., the mother) is not even touched. A fetal magnetocardiogram (MCG) is the registration of a component of the magnetic field generated by the electrical activity of the fetal heart.

Fetal magnetocardiography: clinical relevance and feasibility [PDF]

Physica C: Superconductivity, 2002
We investigated the feasibility of a high-Tc SQUID system for fetal magnetocardiography (fetal MCG) aiming at a system without a magnetically shielded room and cooled by a cryocooler. The targeted SQUID resolution was 50 fT/vHz (1–100 Hz). The research was performed along three lines: environmental noise suppression, cooling and low-Tc experiments ...

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 with sensors based on giant magnetoresistance

Applied Physics Letters, 2011
International audienceBiomagnetic signals, mostly due to the electrical activity in the body, are very weak and they canonly be detected by the most sensitive magnetometers, such as Superconducting QuantumInterference Devices SQUIDs.

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.
