Report of two cases of atrial premature morphology changes suggesting acute myocardial infarction

Two Chinese patients with chest pain were admitted to the First Affiliated Hospital of Zhengzhou University with increased serum cardiac enzymes and troponins levels (cardiac troponin T, cardiac troponin I). Normal QRS complex with normal ST segment in sinus beats presented in their Electrocardiogram. Also, wide and deep QS waves and elevated ST segments were found in atrial premature beats (APBs) and a series of dynamic changes were recorded over time, just as the changes during acute myocardial infarction (AMI). As far as we know, this is the first report about the relationship between the diagnosis of AMI and the changes of QRS complex and ST segment morphology in APBs.
