As a standing segment of all of his lectures, his list of 18 causes of ST elevation have been drilled into our minds. Of note, only ONE of these is myocardial infarction! In this previous Vitals post, we covered causes of troponin elevation; today we are going to cover the causes of ST elevation.
Causes ST elevation:
The Usual Suspects
STEMI
Vasospasm
Pericarditis/myocarditis
Benign early repolarization
Lefties and Righties
Left bundle branch block
Left ventricular aneurysm
Left ventricular hypertrophy
Pulmonary embolism, right heart strain
H’s
Hyperkalemia
Hypercalcemia
Hypothermia
Na+ cHannelopathies
Names

Intracranial abnormalities
Post-cardioversion/post-epinephrine
Aortic dissection
Massive GI bleed

STEMI mimics
The Debrief
Consider dividing up the causes of ST elevation into the following categories:
