What specific ECG changes suggest NSTE-ACS?
Transient ST changes (0.5 mm [0.05 mV]) during symptoms at rest strongly suggest ischemia and underlyingsevereCAD. Marked symmetrical precordial T-wave inversion (2 mm [0.2 mV]) suggests acute ischemia, particularly due to a critical stenosis of the left anterior descending coronary artery.
