Magnetocardiography (original) (raw)
Magnetocardiography (MCG) is a technique to measure the magnetic fields produced by electrical currents in the heart using extremely sensitive devices such as the superconducting quantum interference device (SQUID). If the magnetic field is measured using a multichannel device, a map of the magnetic field is obtained over the chest; from such a map, using mathematical algorithms that take into account the conductivity structure of the torso, it is possible to locate the source of the activity. For example, sources of abnormal rhythms or arrhythmia may be located using MCG.

| dbo:abstract | Das Magnetokardiogramm (abgekürzt MKG) ist die Aufnahme und Darstellung des Magnetfeldes des Herzens, das durch die elektrophysiologische Aktivität der Herzmuskelzellen entsteht. Die Aufnahme erfolgt in der Regel mit hoch empfindlichen Magnetfeldsensoren, so genannten SQUIDs. Die Aufnahme des Magnetokardiogramms ist berührungslos, nicht invasiv und rein passiv. Der Körper wird während der Messung keiner Energie und keiner Strahlung ausgesetzt. Das Magnetfeld des Herzens entspricht exakt seiner elektrophysiologischen Erregung. Da jedoch die Magnetfeldlinien im Gegensatz zu den elektrischen Signalen durch das Körpergewebe nur marginal beeinflusst werden, ist ein sehr exakter Rückschluss auf die elektrophysiologische Funktion des Herzmuskels möglich.
