Title:
METHOD FOR NON-INVASIVE MAPPING OF MYOCARDIAL ELECTRICAL ACTIVITY
Document Type and Number:
WIPO Patent Application WO/2013/062259
Kind Code:
A1
Abstract:
A method for mapping myocardial electrical activity according to one embodiment of the present invention comprises the steps of: measuring electrocardiogram data or magnetocardiogram data; and mapping the degree of the electrical activity of the myocardial surface using the electrocardiogram data or magnetocardiogram data. A signal source of the electrocardiogram data or magnetocardiogram data is the surface potential on myocardium of which the scalar is positive, and the mapping uses a corrected lead field obtained by combining a lead field vector between the surface potential on myocardium and the electrocardiogram or magnetocardiogram data, and a limit matrix obtained by applying the restriction conditions in which a potential source is absent in a specific region.
