It is usually subtle but can sometimes be pronounced and can easily be mistaken for pathological ST segment elevation. Benign early repolarisation can be recognised by its characteristic electrocardiographic features: elevation of the J point above the isoelectric line, with high take-off of the ST segment; a distinct notch at the junction of the R wave and S wave, the J point; an upward concavity of the ST segment; and symmetrical, upright T waves, often of large amplitude. Antecedent myocardial infarction The ST segment elevation associated with acute infarction usually resolves within two weeks of the acute event, but it may persist indefinitely, especially when associated with anterior myocardial infarction.
ST segment abnormalities may be seen in association with cocaine use and are probably due to a combination of vasospasm and thrombosis. 2/7/2008 12:01:44 PM CHAPTER 10 Myocardial Ischaemia Kevin Channer, Francis Morris In clinical practice electrocardiography is most often used to evaluate patients with suspected ischaemic heart disease. When interpreted in the light of the clinical history, electrocardiograms can be invaluable in aiding selection of the most appropriate management. Electrocardiography has limitations.
The degree of ST segment elevation varies between subtle changes of < 1 mm to gross elevation of > 10 mm. V1 V2 V3 V4 V5 V6 Pathological Q waves As the acute myocardial infarction evolves, changes to the QRS complex include loss of R wave height and the development of pathological Q waves. Both of these changes develop as a result of the loss of viable myocardium beneath the recording electrode, and the Q waves are the only firm electrocardiographic evidence of myocardial necrosis. Q waves may develop within one to two hours of the onset of symptoms of acute myocardial infarction, though often they take 12 hours and occasionally up to 24 hours to appear.
