Auto-interference by a demand pacemaker.


Immediately after implantation of a unipolar demand pacemaker, inappropriate inhibition accompanied by instability of the ECG baseline became apparent. Later, higher frequency artifact appeared and the pacemaker fired intermittently in its fixed rate mode, indicating the sensing of severe interference. These phenomena were subsequently found to have resulted form ecposure on the pacemaker surface of a connection between the negative side of the battery and the electronic components.
