Flashcards in UW ECG Course Deck (14):
1

LAD Ddx?

LVH
Inferior wall MI
left ant. Fascicular block

2

RAD ddx?

RVH
Lateral wall MI
left post. Fascicular block

3

How do you assess for LVH?

S wave in V1 OR V2

AND R wave in V5 or V6 > 35mm (small boxes) aka 7 big boxes

1 mm = 1 small box = .04s
5 mm = 1 large box = .2s

4

How do you asses for RVH?

R wave > S wave in V1 and gets overall smaller as you move to V6

5

What is the J point?

Point where ST elevation off the baseline

6

What is a pathological Q wave?

Downward (negative deflection) very big

7

PR interval should be less than?

QRS?

QT?

< .2

< .12

< .4 ?

8

What is a 1st degree AV block?

PR > .2 but NO dropped beats

9

What is a 2nd degree AV block (Wenckeboch)?

Increasing PR interval before dropped beat

10

What is a 3rd degrees AV block?

Atrial rate independent of ventricular rate

No pattern bw P wave and QRS

11

P waves with different sizes and PR intervals indicates what?

Seen in what?

Wandering pacemaker aka Multifocal atrial tachycardia

COPD

12

What is a premature junctional complex?

Describe it

No P wave visible, occurs in the QRS

Narrow, comes from ventricles

13

What is a RBBB?

Look where?

What else is required?

Rabbit ears, R, R’

V2

Inverted T wave

14

What is a LBBB?

Look where?

Rabbit ears

V5, V6
