◉ V1 and V2 are __________ leads anatomically
Answer: septal
◉ These are the anterior EKG leads
Answer: V3 and V4
◉ V3 and V4 are the ____________ leads anatomically
Answer: anterior

◉ Up to 40% of inferior STEMIs are complicated by ______________
(which leads?)
Answer: inferior = II, III, AVF
up to 40% are complicated by right ventricular involvement -->
don't give nitroglycerin without checking
◉ What are the signs that an inferior STEMI may have right
ventricular involvment?
Answer: inferior STEMI (leads II, III, AVF)
ST elevation in V1 (looks at right ventricle)
ST elevation in lead III > lead II
ST elevation in V1 + ST depression in V2
◉ ST elevation in V1 + ST depression in V2 --> you should be
concerned about what?
