| Abstract: | Malfunction of a lithium-powered R-wave inhibited unipolar pulse generator (CPI Model 0505) necessitated removal 15 months after implantation. Examination of the pulse generator in a water bath revealed abnormal function at temperatures above 31.5 degrees C and normal function at temperatures below 31.5 degrees C. CPI suggested that the failure was caused by the 10 kHz timing crystal in the generator. |
