WebT wave abnormalities. T waves are characteristically upright and reflect ventricular repolarisation.. T wave abnormalities may appear on the ECG as flat, inverted, peaked or bifid (initially upright then inverted).. The two predominant changes are T wave inversion and peaked T waves.Flat T waves are generally non-specific and may be linked to … WebCriteria for ischemic T-wave inversions. T wave inversion ≥1 mm in at least two anatomically contiguous leads. These leads must have evident R-waves, or R-waves larger than S-waves. Pathological (infarction) Q-waves. Pathological Q-waves arise arise if the infarction is extensive, which is usually not the case in patients with NSTEMI.
WebECG changes of myocardial injury and ischemia include hyperacute T wave, ST elevation, Q wave, ST depression, T wave flattening as well as T wave inversion (TWI) [ 2, 3 ].
