Verified Answers
Which coronary artery is affected with
Anterior MI
Inferior MI
Lateral MI
Septal MI
Posterior MI - ✔✔LAD
RCA
LCX
LAD
LCX or RCA
Which leads are known as precordial or unipolar leads - ✔✔V1-V6
Limb leads- I, II & III are known as - ✔✔Bipolar leads
Vr, Vf & Vl leads are known as - ✔✔Augmented leads
What is the J point? - ✔✔Known as the area where the S wave changes direction. J point can
be used to determine ST elevation, depression
Delta wave is associated with what? - ✔✔WPW
Osborne wave is associated with what? - ✔✔Hypothermia
, Electrical alternans (alternating amplitude on EKG) of the R - ✔✔Suspect pericardial
effusion/cardiac tamponde
3rd degree heart block/Complete AVB - ✔✔More P waves then QRS's with no relationship
between them. r-r interval will be regular & the P waves will consistently march out, no
constant PR interval
In which sequence does blood flow through the heat valves? - ✔✔Tricuspid, pulmonic,
mitral, aortic
"Toilet paper my a.."
second degree AV block type 2 - ✔✔PR interval is constant & there are more P waves
present than QRS. R-R is regular, P waves march out
