title: Myopotential inhibition of a ventricular demand pacemaker in a patient with Parkinson's disease.
abstract: A patient with severe Parkinson's disease experienced a syncopal attack due to skeletal muscle myopotential inhibition of an implanted ventricular demand pacemaker. The problem was diagnosed with the aid of Holter monitoring, and was corrected by noninvasively programming the pacemaker to a lower sensitivity.
