Anterior infarction
ST elevation, Leads V1, V2, V3, V4
with or without bizarre Q waves
Usually related to occlusion of the LAD branch of the LCA
Lateral infarction
ST elevation, Leads I, aVL, V5, V6
with or without bizarre Q waves
May be a issue of a multiple site infarction
Usually related to obstruction of Left circumflex artery
Inferior infarct
ST elevation, Leads II, III, aVF
with or without odd Q wave
Usually related to RCA occlusion
Right Ventricular infarct
ST elevation (excellent recognized with 1-2mm ST elevation) In Lead V4-R
*generally accompanies inferior MI
r/t proximal occlusion of the RCA
Important motive for hypotension in inferior MI (Recognized with the aid of jugular venous
distension with clear lung fields)
Right Ventricular infarct remedy
Treatment is competitive with reperfusion,
ok IV fluids for right heart filling,
and pacing to hold A-V synchrony if important
Posterior infarct
Tall huge (>zero.04 sec) R wave and
ST depression in V1 and V2 (reciprocal changes)
ST elevation, Leads V7, V8, V9
