The electrocardiogram in patients with acute myocardial infarctions treated with intracoronary Streptokinase infusion.
In 37 consecutive patients with acute myocardial infarction undergoing Streptokinase infusion and acute coronary angiography, the electrocardiographic findings were compared with the findings during angiography. All 15 patients with an occluded right coronary artery demonstrated an electrocardiographic pattern of an acute inferior wall myocardial infarction, and 12 of 13 patients with an occluded left anterior descending coronary artery exhibited a pattern of an acute anteroseptal wall myocardial infarction. In six out of nine instances of an occluded circumflex artery, an inferior infarction pattern evolved, and in three cases, an anteroseptal wall myocardial infarction was demonstrated. precordial ST segment depression more than 1 mm in patients with acute inferior wall myocardial infarction did not correlate with disease of the left anterior descending coronary artery as suggested by others. The specificity of this finding was only 25 percent with a predictive value of 60 percent.
