Model		2450 MHz (PW) exposure to isolated rat and frog hearts and anaysis of beat rate
Details		Isolated rat and frog hearts were exposed were exposed to 2450 MHz (PW-16 Hz or 10 usec pulse width, 10 msec ppps) MW for 30 minutes either synchronized or non synchronized with the ECG. Exposure at 10 W/kg or less had no effect on heart rate. Exposure at 200 W/kg or conventional heating resulted in a transient increase in heart rate, a subsequent decrease in hr, and a corresponding heart muscle temperature increase of ~8 degrees. In an earlier study (Bioelectromagnetics (1994) 15(6):555-561), MW exposure as above at SARs up to 8 W/kg did not affect conduction velocity in frog ventricular muscle (pacemaker cells). Other studies (Bioelectromagnetics 5(2):263-270) showed artifacts due to the metal thermal probes could cause beating artifacts during exposure.
