[Long-term survival in persons with cardiac pacemakers. Study based on 1,159 patients, 499 with regression at 4-10 years].
Analysis of the long-term survival of pacemaker carriers showed a parallelism between two curves: that of the survival in patients treated with a pacemaker as from the second month, and that of a control group with the same age and physical structure. Treatment in the first few years was made problematical by defects in surgical technique: while in 17% of reoperations, the reason was straightforward substitution of the pacemaker owing to wear on the battery, 83% were the consequences of complications. Of these, 23% consisted of shifts in the intracavitary probe, electrode failures, or increase in the threshold. The frequency of infections due to implantation or reoperation was 7,4%, in certain cases with fatal outcome. Bearing in mind that mortality from Adam-Stokes disease was 50% prior to the introduction of pacemakers, it can be maintained that this therapy represents a considerable step forward in cardiology. Mortality was 27% in all patients submitted to implantation.
