[Permanent pacemakers: 15 years' experience].

We report a 15 year experience in the attention of patients with definitive pacemakers. This study includes 200 patients treated from 1964 to 1978, with an age range from 15 to 102 years, who required 329 generators. The predominant cardiopathy was atheroesclerotic (172 cases). We analyze the associated diseases in which hypertension was prominent in 30% of these cases. The most frequent rhythm alteration was atrioventricular block in 72% of the cases, and trifascicular block in 16%. We observed 35 intercurrent complications (17.5%), and the most frequent was infection of the generator bag. Mortality in these patients averaged 11%, being strictly imputable to the pacemaker in only 2%. Eighty patients needed generator change and we report a case who required up to six changes. The implantation of permanent pacemakers for treatment of patients with severe arrhythmias is considered at present secure and effective.

[Use of a temporal cardiac pacemaker in patients undergoing a major non-cardiac surgery].

This is a report of the use of transvenous temporal pacemaker in 18 patients, with an average age of 59.3 years, that under want non cardiac major surgery. They did not have cardiac simptoms but had conduction abnormalities in the preoperative electrocardiogram. A pacemaker was implanted as a prophylaxis against arrythmia during the transoperative and postoperative periods. There was no incidence of transoperative arrythmia. Three patients died in the immediate postoperative period, two due to duffuse carcinomatosis and one due to diabetic acidosis. The average duration of the implanted pacemaker was 12.7 days, and three patients required a permanent pacemaker. Case five is exemplificative of the benefits of the temporal pacemaker, he had a preoperative electrocardiogram showing trifascicular block, he was taken to the operating room and anesthesia was induced, the patient had a cardiac arrest but recovered without secuela; latter on a temporal pacemaker was inserted and the patient had surgery without cardiac problems.
