Fracture of pacing electrode mimicking failure of pulse generator.
To our knowledge, this is the first reported case of spontaneous fracture of a pacing electrode with decreased amplitude of the pacing artifact, failure to capture, and intact sensing. We postulate that the difference in impedance of the pacemaker for sensing and stimulation may account for this phenomenon.
