Implantation of Artificial Cardiac Pacemakers for Bradyarrythmias

Abstract

Two cases-the one with second-degree A-V block and the other with third-degree A-V block-were treated successfully by implantation of artificial cardiac pacemakers. A stress was made on the importance of preoperative temporary cardiac pacing and recordings of His bundle electrogram for selecting patients. The routine measurement of myocardial threshold and analysis of pulse wave-form of generators upon implantation were discussed. In addition, our methodology of following up patients with implanted pacemakers were briefly described. The application of pacemakers to various types of arrythmias is a useful armamentarium provided that they were properly handled with precise knowledge and techniques.
