WebFeb 11, 2024 · Wellens' syndrome refers to specific electrocardiographic (ECG) abnormalities of deeply inverted T-waves in the precordial leads, mainly V1-V3, associated with critical stenosis of the proximal left anterior descending (LAD) coronary artery. Identifying this specific pattern on the electrocardiogram … WebTypically, there is ST segment depression and T wave inversion (or biphasic T waves) in the lateral leads and ST segment elevation (STE) in the precordial leads V1-V3. However, other patterns of ST-T changes may occur. These changes may vary over time and may not necessarily reflect acute ischemia. The ST-T changes secondary to LVH interfere ...

Hyperkalaemia is defined as a serum potassium level of > 5.2 mmol/L. ECG changes generally do not manifest until there is a moderate degree of hyperkalaemia (≥ 6.0 mmol/L). The earliest manifestation of hyperkalaemia is an increase in T wave amplitude.
WebThe abnormalities of T waves can be presented in two critical patterns; the deep inversion of T waves or biphasic T waves in several precordial leads. The changes in T waves commonly occur in leads V2-V3, although they can extend to other precordial leads and persist for hours and weeks ( 4 ).
