Method of examining dynamic cardiac electromagnetic activity

Abstract

A method of examining cardiac electromagnetic activity over a heart for diagnosing the cardiac functions of the heart is disclosed. The method may include constructing a phase diagram of electromagnetic signals over a heart by collecting sets of time-dependent magnetic signals, determining the zeroth and the first derivations of each set of the magnetic signals at a given time, and categorizing the zeroth and the first derivations of the magnetic signals in either of the four phases: (+, +), (−, −), (+, −), (−, +). The method may also include monitoring a wave propagation of the magnetic signals.

1 . A method of examining cardiac electromagnetic activity by monitoring a propagation of a wave of magnetic signals of a heart. 
     
     
         2 . The method of  claim 1 , wherein the magnetic signals are either two-dimensionally or three-dimensionally distributed over the heart. 
     
     
         3 . The method of  claim 1 , wherein the magnetic signals exhibit features of a P-wave, a Q-wave, a R-wave, a S-wave and a T-wave corresponding to an electrocardiography, and the propagation of the P-wave, the Q-wave, the R-wave, the S-wave, the T-wave or a combination thereof is monitored.
