These findings … WebWellens’ sign is a finding that is concerning for a high-grade stenosis of the left anterior descending (LAD) artery. There are two forms of Wellens’ sign on ECG; type one includes biphasic T waves in V2-V3; and type two …
WebIn most cases, the T-waves are also inverted in V2 and V3. These T-wave inversions persist until 10 years of age (sometimes up to 15 years). Thus, T-wave inversions in leads V3R, V1, V2, V3 are normal between 7 days and 10 to 15 years of age. The absence of T-wave inversions in these leads should lead to suspicion of right ventricular hypertrophy.
