A programmable pulse generator with high output option.
A new pulse generator, with a programmable high output option, was implanted in fifteen patients and studied for eight to ten months postoperatively. This feature is designed to combat exit block. It was useful in one patient who developed a form of exit block following a silent myocardial infarction. Muscle stimulation was rare, even though the system is unipolar. The high output option seems to be a desirable feature and should probably be available in all multiprogrammable pulse generators.
