After five years of laboratory development and experimental testing in animals, a rechargeable cardiac pacemaker powered by a specially designed nickel cadmium power cell was ready for human use. The bipolar coaxial pacing catheter connects to the pulse generator with a twist-lock mechanism, obviating the need for tools or ties. The small size of the pulse generator makes it easier to implant than conventional units. Recharging is performed by the patient at home for 90 minutes a week. This report details the early clinical experience with 26 patients who received this unit. All units are functioning and recharging according to specifications, and further clinical evaluation is now under way.
