Radiofrequency-Controlled Catheter Pacemaker

Abstract

THE transvenous endocardial electrode catheter¹ and the radiofrequency induction assembly² have been used for cardiac pacing with success over the past seven years. The catheter electrode has proved to be a satisfactory tool for short-term and long-term pacing and has been particularly useful for gaining immediate control of, and preserving, the heartbeat until installation of a more permanent unit.^{3 , 4} Of the difficulties encountered with its early application, only the transmission of infection via the exteriorized electrodes and perforation of the heart continue to be potentially serious. A recent report describes a method of long-term pacing with the pacemaker buried beneath . . .
