Following repair of an abdominal aortic aneurysm, a 66-year-old man develops severe chest pain, diaphoresis, bradycardia and hypotension. The following is/are true:
A. The electrocardiogram is most likely to show a prominent Q in lead 3 if this is an MI
B. If Q wave is present, the infarct is subendocardial rather than transmural
C. Creatine kinase measurement alone is diagnostic of MI
D. Since bradycardia rarely occurs with MI, another diagnosis should be considered
