For the diagnosis of myocardial infarction (MI) using the QRS complex, the ECG provides only a low sensitivity (25%) but high specificity (close to 100%), but one cannot determine the age of an MI from the QRS complex. Although one cannot determine with certainty the age of an MI (hours, days or even years) from a single ECG, the presence of primary ST-segment abnormalities strongly suggests the diagnosis of acute MI or severe ischemia and the possible need for emergency revascularization. For acute MI, ST elevation>or=5 mm in predominantly negative QRS complexes is the best marker with a sensitivity of 53%, and specificity of 88%. A recent investigation suggests that T wave abnormalities from ischemia can be differentiated from those caused by cardiac memory related to pacing.
