Exposure of frog hearts to CW or amplitude-modulated VHF fields: selective efflux of calcium ions at 16 Hz.
Schwartz JL, House DE, Mealing GA · 1990
Researchers exposed isolated frog hearts to 240-MHz radio frequency fields (similar to some wireless communication frequencies) for 30 minutes to study calcium movement in heart tissue. They found that when the RF field was pulsed at 16 Hz, calcium ions moved out of the heart cells at rates 18-21% higher than normal, but only at very low power levels. This suggests that even weak RF fields can disrupt normal cellular processes in heart tissue when delivered at specific frequencies.
