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.
A pacemaker is implanted under the skin, usually on the left side of the chest below the collarbone. The procedure takes about an hour, and most patients go home within a day. Types of pacemakers vary; some correct a slow heartbeat, while others stop an irregular heartbeat or stop severe heart failure.
