Abstract
AbstractComplete heart block has been observed in 42 (7%) of 603 patients with acute myocardial infarction (AMI) between 1966 and 1969 in this hospital. In addition 11 patients got their complete heart block after resuscitation and are excluded from this material. Of the 42 patients 24 were given isoprenaline and 10 insulin, glucose and potassium. No patients were treated with artificial pacemaker. Twenty‐two (52.4%) of the patients with complete heart block died, compared to a total mortality of 30%. The most adverse prognostic factors were BP below 80 mmHg (12 patients) and syncope (12 patients). Of the 22 patients with posterior infarction 11 (50%) died, compared to 4 (33.3%) of the 12 patients with anterior infarction. Of the 8 patients with posterior and anterior infarction or uncertain localization of the infarct 7 (87.5%) died. Of the 22 patients who died 13 died of shock or cardiac failure, 4 of ventricular fibrillation, 4 of asystole and 1 of a stroke. More information must be collected to demonstrate unequivocally the value of artificial pacemaker in the treatment of heart block in AMI.
