Effects of Electromagnetic Interference (2450 MHz) on Cardiac Pacemakers.
Abstract
Tests were performed to determine the effects of 2450 MHz radiofrequency radiation on implantable cardiac pacemakers from various manufacturers. Of the 25 units tested, 11 had been implanted in large anesthetized dogs and 14 were in air (free field). Most of the pacemakers exhibited some electromagnetic radiation interference under certain test conditions. Of the units tested, the most sensitive cut off--if pulse repetition frequencies were less than approximately 30 pps--at approximately 2 V/m in free-field tests, and at approximately 16 V/m (corresponding to approx. 11 microwave/sq cm average power density from a microwave oven) when implanted.
