==Diagnosis==
[[File:T wave morphology.png|thumb|Types of T wave morphology]]
*Normally upright in 1, 2, V3-V6
*Negative in AVR
*If is greater than 2/3 height of R wave then is abnormal

*Distribution 
**T wave is normally inverted in aVR; sometimes inverted in III, aVF, aVL, V1 
*T-wave inversions in V2-V6 are always pathologic 
*Morphology 
**Inverted, symmetric, 
**Transient changes suggests ischemia without infarction 
**Persistent changes suggests infarction (troponin elevation usually seen) 
*Pseudonormalization 
**In presence of baseline TWI (within 1 month), reocclusion causes normalization of TWI 
**Should be interpreted as evidence of ischemia

==Differential Diagnosis==
===T Wave Inversions===
*[[Myocardial infarct]] (NSTEMI)
*Myocardial ischemia ([[Wellen's]])
*[[Pulmonary embolism]] (RV strain)
*[[LVH]] with strain pattern
*[[Bundle branch block]]
*[[WPW]]
*[[Pericarditis]] (stage 3)
*CNS T waves (diffuse, deep)
*[[ARVD]] (may also have epsilon wave)
*Paced rhythm
