Key result
Magnetocardiography offers a more sensitive approach than rest ECG for detecting myocardial electric activity and diagnosing ischemic heart disease using various analytical methods.
Why the study?
Does magnetocardiography improve the early detection of electromagnetic abnormalities in ischemic heart disease compared to rest ECG?
Does magnetocardiography improve the early detection of electromagnetic abnormalities in ischemic heart disease compared to rest ECG?
Magnetocardiography offers a potentially more sensitive alternative to rest ECG for detecting early electrophysiologic changes in ischemic heart disease.
May support further evaluation of magnetocardiography for ischemia detection; leaves open its clinical role versus ECG pending prospective trials.
Ischemic heart disease (IHD) is one of the leading causes of death in the general population. Ischemia induces changes in the electrophysiologic properties of the myocardium that sometimes cannot be detected with rest ECG, which has a relatively low sensitivity. Magnetocardiography (MCG) which records the magnetic fields generated by the heart, is reported more sensitive for measuring myocardial electric activity. Many analyzing methods using MCG for the diagnosis of IHD are reported. Those methods can be summarized as follows: magnetic measurement of ST and TQ segment shift, spatial dispersion of the magnetocardiographically determined QT intervals (QT dispersion), ST current angle rotation of magnetic field (isomagnetic map) at rest or in exercise magnetocardiography, analyzing current arrow map during ventricular repolarization, and analyzing the integral values of reporalization In this review we will given an overview of the current status of MCG methods for the diagnosis of IHD.

Watanabe et al. (2008) conducted a review in Ischemic heart disease. Magnetocardiography (MCG) vs. Rest ECG was evaluated. Magnetocardiography offers a more sensitive approach than rest ECG for detecting myocardial electric activity and diagnosing ischemic heart disease using various analytical methods.
