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") #Deep #TWaveInversions #TWI #Differential #Diagnosis #Causes #Cardiology #ECG #EKG #Electrocardiogram
