Scintigraphic evaluation of regression of abnormal Q waves in myocardial infarction.
نویسندگان
چکیده
We report regression of the abnormal Q waves of an inferior old myocardial infarction after an additional anterior acute myocardial infarction, and demonstrate the scintigraphic correlation and chronological course of this phenomenon. Scintigraphic findings in the present case here may contribute to an interpretation of regression of abnormal Q waves in myocardial infarction.

Technetium-99m-pyrophosphate (99mTc-PYP) has been used, in combination with thallium-201, to estimate the site and extent of myocardial infarcts. We report a case of acute myocardial infarction with severe coronary disease in which the distribution of 99mTc-PYP was extensive. A 78-year-old man presented with dyspnea, and a diagnosis of non-ST-segment elevation acute myocar...
