Magnetocardiography: Early Diagnostic of Heart Diseases

Abstract

Noninvasive screening technique to identify cardiac disease in its early phase is developed. Magnetic imaging of cardiac action currents is a new and an ideally suited technology for testing the level of local electric heterogeneities of myocardium. Magnetocardiography (MCG) has the potential to make a valuable contribution in basic examination and analysis of biosignals of a heart, in particular whilst all vector components are used, vast spatial coverage and excellent signal quality. Browsing the data for the sake of reliability by QT-interval can be useful for the better reproducibility of high performance MCG. MCG in therapeutic practice can be use to address the following objectives: а) determining presence and intensity of myocardial ischemia, b) assess effectiveness of antianginal therapy; c) assess the risk of paroxysm of ventricular tachycardia; d) objectivize presence of cardiac deficiency.
