Computer simulation of the heart magnetic field dynamics.
A personal-computer based model, which enables the investigation of the correlation between the temporal dynamics of the magnetic field distribution and electrophysiological processes during ventricular depolarisation, has been tested. The activation sequence following a stimulus to the atrioventricular node or directly to the ventricular myocardium can be simulated in isotropic conditions and visualised in a three-dimensional presentation. The corresponding behaviour of the distribution of the normal component of the magnetic field is calculated using a simple algorithm. Colour animation is used to observe the simulated magnetic field dynamics and to compare them with measured data.
