[Colliquation necrosis of the skin caused by a cardiac pacemaker]. 1985

H Kietzmann, and T Henseler, and J M Schröder, and H Polster, and M Krämer

In two patients with cardiac infarction of a medical intensive care unit blisters developing into deep necroses were observed on the upper extremities and adjoining regions of the trunk within the first days of treatment. Clinical findings and histology indicated extensive caustic artefacts. The cause for the initially mysterious event was found to be a defect in the extracorporeal cardiac pacemaker. Defective isolation had lead to a continuous current potential between pacemaker cover and electrode. The resulting electrolysis caused a dramatic increase of pH on the moist body surface underneath the pacemaker. As a result of the pH shift caustic damage with extensive dermal necroses was observed.
