Study Type		In Vitro
Model		1 GHz (CW, AM-0.5 Hz and 16 Hz) exposure to isolated frog heart tissue and analysis of signaling
Details		Isolated atrial strips of frog heart were exposed to 1 GHz (CW or AM at 0.5 Hz or 16 Hz) for 32 minutes in a stripline waveguide at SARs from 3.2 uW/kg to 1.6 W/kg. AM at 0.5 Hz was in synchrony with the electrical stimulus applied to the presentation. No effect of RF was observed on the movement of calcium ions or on the contractile force in isolated atrial strips of the frog heart. The authors stated that the negative results contradicted previously reported findings from the same laboratory showing that 16-Hz AM RF fields increased calcium efflux from intact frog hearts (#190).
