WebThe T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most … WebStage 1 is characterized by diffuse upward concave ST-segment elevation with concordance of T waves, ST-segment depression in aVR or V 1, and low voltage. The PR-segment depression is usually seen in the leads with ST-segment elevations. Stage 2: ST segments return toward baseline with flattening of the T waves. Stage 3: T-wave inversion.
WebST-segment and T-wave abnormalities (for example T-wave flattening or elevation, or T-wave inversion). Do not rule out stable angina on the basis of a normal resting 12-lead ECG. Do not use exercise ECG to diagnose or exclude stable angina for people without known coronary artery disease (CAD).
