To deactivate an ICD or alter pacemaker function, a magnet has to have a field strength of 10 gauss (a unit of magnetic strength) or greater next to the surface of the device. A magnet in a stereo speaker has a field strength of 100 gauss at the surface - but 0 gauss 6 inches away.
In the magnet response mode, Boston Scientific pacemakers are paced at a magnet rate of 100 bpm at EOL with an AV delay of 100 ms. The third pulse during the magnet test is issued at 50% of the programmed pulse width to allow the clinician to evaluate the safety margin.
