Abstract
The admission electrocardiogram (ECG) was studied in 898 patients admitted to a coronary care unit over two years. The diagnosis made from this tracing was compared with that made at the end of the patient's stay. About half the cases of recent myocardial infarct were diagnosed from the admission ECG, but accuracy rose to 83% with serial ECG's in the unit. The ECG is important but not entirely reliable in the early detection of acute myocardial infarction, which should be largely a clinical diagnosis.
