AbstractThe contribution of the electrocardiogram to the clinical judgment used by the physician in the emergency room to determine the necessity for hospitalizing patients was evaluated. Thirty-five percent of all 1,578 patients with presumed myocardial infarction referred to the Chaim Sheba Medical Center, Tel Hashomer, Israel, for a one-year period had subsequently diagnosed myocardial infarctions. The ECG in the emergency room detected only 65 percent of these. The physician's clinical judgment was impressive in his decision to admit to the hospital almost all of the remaining 35 percent, while not admitting very many of the patients who did not have subsequently diagnosed myocardial infarctions. When the myocardial infarction was not evident on the ECG and the abnormalities on the tracings were identical for patients with subsequent myocardial infarctions and those without, again the physician made the right choice more often than the wrong. The follow-up ECG also attested to the good judgment of the physician in the emergency room. Of the emergency room ECGs of patients without subsequent myocardial infarctions who were admitted to the hospital, 17 percent showed myocardial infarction by follow-up, while this happened to only 2 percent of those denied admission.
