What is Persistence appearance of the following sign in ECG in a case of Myocardial infarction is suggestive of: and explain in detail?
Ans. B. Left Ventricular Aneurysm.ECG in the image shows: Left ventricular AneurysmProgression of ECG changes in Myocardial Infarction.* The earliest presentation of acute myocardial infarction is the hyperacute T wave, which is treated the same as ST segment elevation.In practice this is rarely seen, because it only exists for 2-30 minutes after the onset of infarction. Hyperacute T waves need to be distinguished from the peaked T waves associated with hyperkalemia.* In the first few hours the ST segments usually begin to rise.* Pathological Q waves may appear within hours or may take greater than 24 hr.* The T wave will generally become inverted in the first 24 hours, as the ST elevation begins to resolve.* Long term changes of ECG include persistent Q. waves (in 90% of cases) and persistent inverted T waves.* Persistent ST elevation is rare except in the presence of a Left ventricular aneurysm.
