<ol>
<li>
Typically the normal ECG shows progression of T-wave size across the precordial leads & the T-wave in V1 is inverted or flat</li>
<li>
A large upright T-wave in V1 can be considered normal when there is high voltage/LVH or LBBB</li>
<li>
A new upright T-wave in V1 can be indicative of significant atherosclerotic disease</li>
<li>
If the T-wave in V1 is larger than the T-wave in V6 have a high suspicion for myocardial disease</li>
<li>
A new tall upright T-wave in V1 has ~84% specificity for ischemic heart disease (Barthwal)</li>
