How long does it take for 15-20 minutes
irreversible cardiac damage to
occur with complete occlusion
of coronary arteries?
STEMI is identified by ST segment elevation on EKG
indicating complete blockage of a coronary artery
What is the difference between
STEMI and NSTEMI? NSTEMI does not produce ST segment elevation
and is associated with a partial blockage of a
coronary artery
Q wave MI - pathological, infarction is usually
prolonged and results in necrosis
What is the difference between
a Q and non Q wave MI? Non Q wave MI - characterized by ST segment
depression, usually reversible; reperfusion is
spontaneous

with occlusion I'm the proximal
LAD and may damage the let
ventricle
This type of infarction occurs Left lateral wall infarction
with occlusion is the LCX and
often causes damage to the
anterior wall as well

causes conduction
malfunctions
This type of infarction occurs Right ventricular infarction
with occlusion of the proximal
section of the RCA and
damages the right ventricle
and inferior wall
This type of infarction occurs Posterior wall infarction
with occlusion of the RCA or
LCX and may be difficult to
diagnose
