ST elevation
Last reviewed 11/2022
ST elevation occurs as follows:
- an upwardly convex and elevated ST segment indicates acute myocardial infarction or variant (Prinzmetal's) angina
- the affected leads indicate the area of affected myocardium
- anterior damage shows in the V leads, and inferior in III and VF
In pericarditis the ST segment is elevated, but it is upwardly concave and widespread.
Other causes of ST elevation include (1):
- cardiac trauma
- ventricular aneurysm or large chronic myocardial infarct (at rest, exercise induced or aggravated)
- cardiomyopathies including hypertrophic cardiomyopathy
- left bundle branch block
