PURPOSE:To prevent a comparing circuit from detecting a pacing pulse and the after potential succeeding it without providing a switching circuit not to detect the pacing pulse. CONSTITUTION:A pacing pulse generating circuit 9 is connected to a pulse reducing circuit 10. The output signal from the pulse reducing circuit 10 is connected to the input side of a comparing circuit 6. The pulse reducing circuit 10 has the function to apply a reducing pulse having the polarity opposite to that of the positive or negative unipolar potential judged by the comparing circuit 6 and the potential larger than the input signal to the comparing circuit 6 and prevents the comparing circuit 6 from receiving the input signal with a preset value or above when a pacing pulse is outputted to an input/output terminal 2 from the pacing pulse generating circuit 9. |
