WebIn pulmonary embolism, T wave can be symmetrically inverted at V2 to V4 leads but sinus tachycardia is usually the more common finding. T wave inversion is only present in 19% of mild pulmonary embolism, but the T inversion can be present in 85% of the cases in severe pulmonary embolism. Besides, T inversion can also exists in leads III and aVF.

WebIschemic ST-T changes. Ischemia affects the plateau phase (phase 2) and the rapid repolarization phase (phase 3), which is why ischemia causes changes to the ST segment and T-wave (ST-T changes). The ST segment may be either elevated or depressed. The T-wave may diminish in amplitude (flat T-waves), become negative (T-wave inversion) or … WebIn the intermediate leads, V2 and V3 the T wave is often inverted in early childhood and there is a progression to the T wave becoming upright in the sequence V3, V2, V1. To illustrate the point, 50% of normal 3–5 year old children will have inverted T waves in V2 but in the 8–12 year age group inverted T waves in V2 will be present in only 5–10% of individuals.
