This standard specifies test methods appropriate to many interference frequencies, whether high or low, near or far afield. The standard may specify performance limits or require disclosure of performance in the presence of electromagnetic emitters, where appropriate. It provides manufacturers of electromagnetic emitters with information about the level of immunity to be expected from active implantable cardiovascular devices.

1. This standard and the conformance of emitters to the relevant human exposure safety standards and pertinent regulatory emission requirements (e.g., those of the U.S. Federal Communications Commission, or FCC). Compliance with biological safety guidelines does not necessarily guarantee EM compatibility with pacemakers and ICDs. In some cases, the reasonably achievable EM immunity performance for pacemakers and ICDs falls below these biological safety limits.

2. The potential for emitter equipment to interfere with a pacemaker or ICD is complex and depends on several factors including: frequency content of the emitter; modulation format; power of the signal; proximity to the patient; coupling factors; and duration of exposure.

3. This standard addresses the EM compatibility of pacemakers and ICDs up to 3,000 MHz and is divided in several sections: a) 0 Hz ? ¿ < 450 MHz; b) 450 MHz ? ¿ < 3,000 MHz; c) ¿ ? 3,000 MHz.
