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 …
