ST depression means below baseline seen in ischemia.

ST elevation means above baseline seen in impending infraction as seen in vasospastic condition.

Hope they help.

pericardiocentesis),
Injury (AMI, contusion), Osborne waves (hypothermia), Non-occlusive
vasospasm (prinzmetal’s)



> Depressed ST-segment: causes DEPRESSED ST:
Drooping valve (MVP)
Enlargement of LV with strain
Potassium loss (hypokalemia)
Reciprocal ST- depression (in I/W AMI)
Embolism in lungs (pulmonary embolism)
Subendocardial ischemia
