Abstract

A method of examining cardiac electromagnetic activity over a heart for diagnosing the cardiac functions of the heart is disclosed. The method includes collecting a plurality of sets of spatially distributed, time-varying magnetic field signals of the heart of a subject, wherein the magnetic field signals exhibit features of at least a wave, identifying a time corresponding to a local maximum intensity of the magnetic field signals of the wave at each measurement position and plotting a temporal evolution of the local maximum intensity of the magnetic field signals during a time interval of the wave.
