title: Pacemaker contact sensitivity.
abstract: In a patient who had 4 cardiac pacemakers implanted and removed, pruritus, redness, and swelling of the skin overlying the pacemaker developed at intervals of 6 weeks to 17 months after insertion. Patch testing showed a 2+ reaction to titanium. The positive result of this test, the titanium case of the generator, and the history of multiple local reactions around the generator site pointed toward contact sensitivity to the pacemaker. Although a review of the literature indicates that this problem is rare, it is of extreme importance to the patient with pacemaker contact dermatitis.
