Summary

A magnetocardiograph (MCG) is a device capable of recording of magnetic fields arising from the electrical activity of the heart with traces similar to an electrocardiogram (ECG). This system was developed as a noninvasive, non-contact diagnostics of obstructive coronary artery disease (CAD), and especially of lack of oxygen in the heart as in a heart attack. The overall objective of this study is to demonstrate the efficacy of this MCG device for the detection and diagnosis of lack of oxygen of the heart in patients with chest pain.

Conditions

  • Myocardial Ischemia

Interventions

DEVICE

Magnetocardiograph

MCG and ECG recordings sequentially at the four pre-defined bed positions and watches the real-time magnetocardiogram traces on the computer screen. At each position, nine sensors record MCG data, thus forming a 3 x 3 point grid square with point-to-point separation of 40 mm. The number of cardiac cycles recorded at each position should be adequate for signal averaging. Recording time per position is typically 90 seconds. At the end of 4 sequential recordings, raw, unfiltered MCG data are stored.
