T-wave inversion in the anterior precordial leads is well documented in athletes and appears to be related to age and ethnicity. However, the prevalence and significance of isolated inferior t-wave inversion is less certain.Aims: To describe the prevalence and significance of isolated inferior t-...
Although T-wave inversions are nonspecific, in the appropriate clinical setting, the pattern of negative biphasic T-waves or T-wave inversion in V2-V3 can indicate critical stenosis of the left anterior descending coronary artery (i.e. “anterior Wellens sign”). Recently tall T-waves in V2-...

A 1-mm T-wave inversion was seen in both III and V1 in 11/97 (0.113) of patients with PE vs. 9/194 (0.046) controls (PD 0.07 [95% confidence interval (CI) 0.01–+0.14]; K = 0.7). Other criteria for anterior and inferior T-wave inversions were less common in PE (0.04–0.05...
A repeat ECG done 24-hours later also showed T wave inversion in the precordial leads (Figure lb). Predischarge angiogram done on the 7th day of admission showed an absence of thrombus or atherosclerotic lesions throughout the entire left coronary system. The patient had an anatomically wrapped...
We present the case of a 41-year-old man who developed myopericarditis after receiving the Pfizer COVID-19 vaccine. The patient experienced a sudden onset of chest and abdominal pain 16 days after vaccination. Electrocardiogram findings revealed deep T-wave inversion and...
The presence in lead aVF of either a diagnostic Q-wave or T-wave inversion was seen in 30 of 35 patients with inferior MI (sensitivity of 86%) compared with only 12 of 131 patients with uncomplicated LBBB (specificity 91%). Thus, these criteria are potentially useful for the diagnosis of...
In the clinical population, other ECG abnormalities (i.e., Q waves and T wave inversion) accompanying ER were much more common in the inferior leads than the lateral leads (8% vs 1%, p < 0.001). While age, gender, heart rate, and ethnicity significantly affected the prevalence of ER ...

The presence of either a Q-wave or T-inversion in aVF appears to be useful in predicting past inferior infarction in patients with LBBB. The combination of the two, though rare, has a high positive predictive value.doi:10.1016/0735-1097(95)91524-2Charles L. Laham...
