Between October, 1981, and April, 1983, 200 pacemakers were inserted at Rhode Island Hospital. Forty‐five bipolar polyurethane leads (Medtronic 6972) were positioned in the right ventricle. Three (6.6%) of these leads presented 15 to 18 months post‐implant with insulation failure. The manifestation was inappropriate inhibition of the pacemaker. No obvious cracking was visible on X‐ray or during surgery. All the leads had low impedance, indicative of insulation failure.
