During past 13 years, 115 patients underwent the implantation of cardiac pacemaker. Nintythree out of these patients survived over 6 months after the implantation of pacemaker. The change of NYHA functional classification and social rehabilitation after pacemaker implantation were studied in 82 survivors and the cause of death was analysed in 11 patients who died. The causes of death were as follows; congestive heart failure in 3, primary myocardiopathy in 1, sudden death in 1, cancer in 2, apoplexy in 1, pneumonia in 1, perforative peritonitis in 1, and nephritis in 1. Significant improvement of symptoms estimated by the NYHA functional classification was obtained in 69 patients. In 7 patients, the NYHA classification was not changed or slightly improved. In these patients, 3 had tachycardia and 4 had congestive heart failure preand postoperatively. The rate of social rehabilitation was 62.0%. This value disclosed rather unsatisfactory in comparison with the postoperative NYHA classification. On the other hand, 2 female patients with complete A-V block were safely delivered after implantation. Their rate-output curves made flat type which showed that cardiac output was independent on the wide range of pacing rate.
