T Wave Inversions

• Myocardial infarct (NSTEMI)
• Myocardial ischemia (Wellen's) - T waves go up, then down
• Hypokalemia - T waves go down, then up (or camel humped, one upright TW and upright U-wave in severe hypokalemia)
• Pulmonary embolism (RV strain)
• LVH with strain pattern
• Bundle branch block
• WPW
• Pericarditis (stage 3)
• CNS T waves (diffuse, deep)
• Arrhythmogenic right ventricular dysplasia (may also have epsilon wave)
• Paced rhythm
• Elevated intracranial pressure
