Camm, AJ, Henderson, R, Brisinda, D et al. (4 more authors) (Cover date: November-December 2019) Clinical utility of magnetocardiography in cardiology for the detection of myocardial ischemia. Journal of Electrocardiology, 57. pp. 10-17. ISSN 0022-0736
Abstract
Magnetic field maps from (A) subjects without ischemia, showing a bipolar field map throughout the cardiac cycle, and (B) patients with acute coronary syndrome in whom a distorted, fragmented or multipolar field map characterizes active myocardial ischemia. Maps were recorded with a 15-channel magnetometry device and display the magnetic field distribution at the point of maximum rate of change between the Q and R peaks (QR) and between the R and S peaks (RS).
The dipoles observed in subjects without ischemia are generally aligned in the same direction and have only a single positive (red) and single negative (blue) pole. The images from ischemic patients are generally more complex. A wider spread of angles and pole to pole distance, and the presence of more than two peaks are features that generally indicate ischemia.
