ST elevation

An electrocardiographic abnormality in which the ST segment (at the J point) is displaced above the isoelectric baseline (typically ≥1–2 mm), reflecting altered ventricular repolarization.

Causes

• Myocardial and cardiac causes

  • Transmural myocardial infarction (ST-elevation myocardial infarction, STEMI)

  • Pericarditis

  • Myocarditis

  • Ventricular aneurysm

  • Left ventricular hypertrophy

• Electrical and conduction disorders

  • Brugada syndrome

  • Benign early repolarization

• Coronary vasospasm (Prinzmetal angina)

• Hyperkalemia

• Pulmonary embolism

• Hypothermia

• Takotsubo cardiomyopathy
