Abstract
Apparatus and methods are disclosed for reducing the potentially harmful effects of electromagnetic waves on an implantable medical device. In one embodiment of the present invention, an implantable medical system comprising a dual threshold magnetic sensor capable of detecting an elevated magnetic field is disclosed. The sensor can comprise a solid-state sensor capable of detecting a static magnetic field in excess of about 1500 Gauss. The magnetic sensor can be operatively coupled to electronics that are capable of altering the operation of the system upon detection of an elevated magnetic field by the magnetic sensor.
