Tests were performed to determine the effect of 3050 MHz radio- frequency radiation on cardiac pacemakers. Five pacemaker models were implanted in large dogs and tested in each of two laboratories. The electrocardiographs of each animal were continuously monitored for various exposure conditions. Most of the pacemakers exhibited some electromagnetic radiation interference EMI under certain conditions of these tests. The most sensitive unit, of those tested, cut off at approximately 100 V.m. at pulse repetition frequencies less than approximately 35 pps--while one pacemaker exhibited no effects from EMI throughout these tests.
