Reduction of pacemaker-induced pectoral muscle stimulation using an insulating patch.

ABSTRACT

An 82-year-old female patient was admitted for replacement of her pulse generator battery which had reached an end-of-life situation. The old unipolar leads were retained. Pectoral muscle stimulation began shortly after implantation. Though complete abolition of muscle stimulation was not achieved, an insulating patch placed between the muscle and the pacemaker can reduced stimulation.
