The heart block and bradyarrhythmia with or without Stokes-Adams attacks are serious, usually terminal events and the immediate mortality is very high. Stimulation with an artificial pacemaker is now an accepted form of treatment in cases of Stokes-Adams syndrome in which medication in unable to produce any lasting improvement. Permanent pacemaker therapy is indicated in these circumstances. The purpose of this report is to describe the successful use of pacemaker in 3 cases of Stokes-Adams syndromes and a case of sinoatrial block with bradyarrhythmia at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University School of Medicine. Electrode catheter was passed through the right external jugular vein and attached to the endocardial surface of the right ventricle. In case 1, fixed type generator was used at first and for the case 2, 3, 4, and case 1 at second, demand type generators were used. The bipolar electrode catheters were used for the three cases and unipolar electrode catheter for case 4. The results of immediate and late period were satisfactory.
