<<Electromagnetic Interference and Pacemakers.url>> << EMF Interference with Cardiac Pacemakers.htm>> Phil my understanding is that EMF's can affect pacemakers and the effect varies from model to model. Where there is interference, pacemakers usually revert to a fixed pacing mode and although it can be uncomfortable this is not dangerous. Some people with unusual heart rhythms have special pacemakers fitted and these could be adversely affected, but since this is a special pacemaker the physician would warn the patient about it.

I have been asked by an individual who is to be fitted with one of these devices about areas on our site which may interfere with it. We are a large site manufacturing chemicals with control rooms, radio comms etc. Ta Phil This e-mail and any files transmitted with it, are confidential to National Grid and are intended solely for the use of the individual or entity to whom they are addressed.
