User :   Do Depressed ST waves on an EKG always mean blockage?
Doctor :   the severity of depression of ST waves are more significant
Doctor :   and also the leads in which they are found matter the most
User :   I see ....and from the least to most severe causes what might they be

Doctor :   the most common cause of depression of ST waves is angina (reversible blockage of blood flow)
Doctor :   and vasospastic angina
Doctor :   a complete MI (myocardial infarction ) will cause a ST elevation
User :   can stress or anxiety cause these changes?
Doctor :   stress and anziety can precipitate a angina, and this in turn can cause ST depression
Doctor :   but alone without presence of CAD, the 2 conditions cannot cause such changes
User :   No presence of CAD...but Depressed ST waves in a female
