Deep T Wave Inversions - Differential

Normal variants 

  A. Juvenile T wave pattern 

  B. Early repolarization 

Myocardial ischemia/infarction 

Takotsubo (stress; apical ballooning) cardiomyopathy 

Cerebrovascular accident (especially intracranial bleeds) and related neurogenic patterns 

Left or right ventricular overload 

  A. Typical patterns (formerly referred to as 'strain" patterns) 

  B. Apical hypertrophic cardiomyopathy (Yamaguchi syndrome) 

Idiopathic global T wave inversion syndrome 

Secondary T wave alterations: bundle branch blocks, Wolff-Parkinson-White patterns 

Intermittent left bundle branch block, preexcitation, or ventricular pacing ("memory T waves")
