V3
V4

4

Artery Responsible for anterior wall infarctions

LAD (anterior interventricular)
leads V1-V6

5

Artery responsible for inferior wall infarction (RV infarction)

Right Coronary artery
II
III
AVF
V3-V6

6

Artery responsible for lateral wall infarction

Circumflex artery
I
AVL
V5
V6

7

Artery responsible for posterior wall infarction

Posterior descending artery (posterior interventricular artery
V1-V3

8

What lead do we call the transition lead?

V3

9

What leads do we want to look for normal P waves in?

II
V1

10

Four questions for sinus rhythm?

1. P married to QRS
2. QRS narrow
3. P waves present
4. Rhythm is regular

11

P wave looks like it hurts to sit on

R atrial enlargment
p pulmonale

12

P wave is notched, or looks like an "M"

Left atrial enlargement
P Mitrale

13

Rate greater than 100

tachycardia

14

If you see narrow QRS tachycardia that is irregular, what three things are you thinking?

A fib
MAT
atrial tachycardia with variable AV conduction

15

If you see a regular tachycardia with narrow QRS, whats the next thing you should look for?

P waves
if you have them, look to see if atrial rate is greater than ventricular rate. Yes=atrial flutter
No=SVT

16

Define bradycardia

HR less than 60

17

Mild global ST elevation

LVH

18

An EKG that is irregularly irregular
no discernable p waves

atrial fibrillation

19

Differential of a NARROW COMPLEX irregular tachycardia (3 things)

a fib
a flutter with variable AV conduction
multifocal atrial tachycardia (MAT)

distinguishing between these three is based on evaluation of ATRIAL activity

20

narrow complex irregular tachycardia
with regular atrial activity

atrial flutter
look for sawtooth pattern

21

narrow complex irregular tachycardia
associated with irregular atrial activity, and the p waves have at least three different morphologies

MAT
seen in patients with COPD

22

narrow complex irregular tachycardia
not associated with any notable atrial complexes at all - irregularly irregular

atrial fibrillation

23

Shit indicative of Left ventricular hypertrophy

QRS in V4-V6 jumping off the page
peaked t waves
mild global st elevation

24

premature beats with wide qrs complexes

PVCs
premature ventricular contractions

25

ST elevation seen in inferior leads

leads II, III, AVF
STEMI
(what artery would be associated with this? RCA)
(where would we see ST depression? I and AVL)

26

Normal QT interval?

.35-.50 sec

27

prolonged QT interval associated with

torsades (polymorphic Vtach)
MI?

28

wide, fast QRS complexes

ventricular tachycardia

29

Large R in V1, V2, no real transition complex in V3

Right ventricular Hypertrophy

30

What points you towards a PAC

PAC= premature atrial contraction
early P wave. P wave is fucked up. qrs narrow. may or may not conduct through ventricle.

31

What does stemi stand for

st elevation myocardial infaction

pay attention to what leads you see the elevation in. then think about what arteries supply that area.

32

what does the qrs complex look like in pvc

wide complex

33

V fib

just looks fucked up.
