Webb7 juli 2024 · Wellens syndrome describes a pattern of electrocardiographic (ECG) changes, particularly deeply inverted or biphasic T waves in leads V2-V3, that is highly specific for critical, proximal stenosis of the left anterior descending (LAD) coronary artery. It is alternatively known as anterior, descending, T-wave syndrome. WebbThese progressive changes can correlate with rising potassium levels. For example, peaked T waves might correspond with a potassium level of approximately 6, whereas cardiac arrest generally occurs at higher levels. Note how the PR and QRS lengthen in hyperkalemia until the patient develops a “sine-wave” pattern EKG

Webb1 juli 2015 · Causes Of T Wave Abnormality On ECG Pathological causes include: Ventricular hypertrophy. Strain on ventricles can cause T wave inversion.
