Abstract
Three pacemaker (CPI Delta 925) patients of Sick Sinus Syndrome had the thermal rehabilitation. The device for rehabilitation was Microthermy ME 100, 50 made by OG Giken. The main ultra high frequency bands consisted of 2450 MHz. After rehabilitation no pacemaker output was detected in all three cases. No interrogation worked between the programmer and the pacemaker. After programming stat I mode VVI pacing began and DID pacing could be programmed. Inhibition of output is one of the most dangerous problems in EMI. This Microthermy should not be used for pacemaker patients. Both medical associates and patients should know the effect of EMI on pacemaker.
