Modification of Heart Function with Low Intensity Electromagnetic Energy

Abstract

Three groups of frogs were exposed to pulsed modulated radio frequency electromagnetic (EM) energy. One group was subjected to alternating ten-minute periods of energy exposure and sham exposure, with the exposure pulses synchronized with the rise of the R-wave. A second group was subjected to alternating ten-minute periods of energy exposure and sham exposure, with the exposure pulses synchronized with the T-wave. The third group was sham-exposed controls. The data indicated that rate of change of beat is influenced by exposure to EM energy at incident average power densities of 3 micro-watts/cm. Synchronization of the energy pulses with the phase of the cardiac cycle is of consequence.
