Measurement of the magnetic field of the heart, produced by the same ionic currents that generate the electrocardiogram, and showing characteristic P, QRS, T, and U waves.


(1) Measurement of the magnetic fields (MFs) produced by electrical activity in the heart using an extremely sensitive device, such as a superconducting quantum interference device (SQUID). Multichannel measurement of the MF with mathematical algorithms allows mapping of the conductivity structure and localisation of arrhythmias in the heart.
(2) The recording of the heart’s magnetic field by a magnetocardiograph, see there.


n the map-ping of the electromagnetic field surrounding the heart.
