[Magnetocardiography in clinical practice: algorithms and technologies for data analysis].

This methodological work is the first part of series of papers dedicated to the modern perspective method of non-invasive diagnostics in cardiology--magnetocardiography. Definition of magnetocardiography method is given, levels of magnetocardiography data analysis as well as electrophysiological models are described. The most informative biomarkers and technologies of qualitative and quantitative interpretation of current density distribution maps and curves of total current magnitude are presented. The step-by-step algorithm, which was used for the MCG-data analysis, is proposed.
