Abstract

1. Permanent pacemakers were implanted in cases of Adam-Stokes syndrom, congestive heart failure, or low output syndrom, caused by chronic advanced AV block or recurrent SA block (or simusarest) more than 4 weeks duration. 2. Mortality rate could not be reduced by permanent pacing. Because the mortality rate of these bradyarrhythmia is much higher in the acute phase than in the chronic phase. 3. Permanent pacing clearly prevented Adam-Stokes attacks and showed beneficial effect on prevention of sudden death, and improvement of congestive heart failure or general morbidity. 4. Adams-Stokes attack during the angina in case of variant form of angina pectoris is not prevented by pacing. Pacemaker implantation is also useless in cases with severe myocardial damage and congestive heart failure. 5. Implanted pacemakers may cause some uncomfortable complications, including fatal hazard. Futher development of apparatus, in its reliability and mode of stimulation is required.
