Effects of Electromagnetic Interference on Implanted Cardiac Devices

Cardiac pacemakers and defibrillators are remarkable devices with the ability to provide marked symptom relief and life-saving therapy. An ever-expanding list of indications continues to enlarge the pool of patients who live with implantable devices. Intrinsic to the function of these devices is the ability to sense intra-cardiac signals. An unfortunate by-product is the potential for electromagnetic energy in the environment to interact with and disturb the normal functioning of these devices. This chapter will review the way electromagnetic interference (EMI) can affect cardiac devices and then discuss specific situations and optimal techniques to minimize the chance of untoward interaction.
