Pseudonormalised ST segment

A pseudonormalised ST segment occurs where the baseline ECG shows ST depression (e.g. due to LVH) and the new ECG has ST elevation that is just enough to return the ST segment back to the ‘normal’ baseline. It is not normal. This is a subtle but important change that can suggest acute coronary occlusion.
