[The effect of temporary cardiac stimulation on the course of acute myocardial infarct].
The authors analyzed retrospectively the course of acute myocardial infarction in 165 patients, who needed temporary pacing. Medicamentous influencing with Atropine was not very effective and isoprenaline influencing with atropine was not very effective and isoprenaline was used only to brigade the time before the electrode was introduced. From the whole group, 36 patients were selected who had been admitted to the coronary unit within 4 hours after the development of pain. The authors investigated the development and regression of impaired conduction and investigated whether early admission, early diagnosis of bradyarrhythmia and early introduction of temporary pacing affect the patients' prognosis. In the group of patients admitted within 4 hours pacing was needed on admission by 25% of the patients and in the group admitted later by 75.9%. In the majority of early admissions the authors investigated the development of disorders in the course of the first 24 hours. Early admission did not affect the mortality which is high and differs by the site of the infarction. In infarctions of the lower wall 27.3% of the early admissions died and 32.1% of those admitted after the 4th hour. In infarctions of the anterior wall in the group admitted within four hours 57.1% died and in the group admitted after 4 hours 67.3%. The high mortality is associated with the site but in particular with the extent of the necrotic focus.
