Examine the ECG provided below
a) Describe the abnormalities on the ECG
b) List 2 potential causes
a) Describe the abnormalities on the ECG
Tachycardia
Intraventricular conduction defect probably RBBB Widespread ST elevation
b) List 2 potential causes
Acute myocardial infarction (extensive)
Maybe myopericarditis
There is little to discuss. There are many potential causes for ST elevation, but fewer for ST elevation with bundle branch block. I can think of only the following:
The above ECG was borrowed gratefully from the STEMI collection at LITFL. Unfortunately there is no tachycardia, but the spirit of the question is preserved I hope.
There is an excellent paper to help you generate differentials about ST segment changes: Wang, Kyuhyun, Richard W. Asinger, and Henry JL Marriott. "ST-segment elevation in conditions other than acute myocardial infarction." New England Journal of Medicine 349.22 (2003): 2128-2135.
