Flashcards in EKGs Deck (19):
1

LAFB

LAD, qR (I, aVL), rS (II, III, aVF), large S (V4-V6), poor R wave progression.
No other reason for LAD.

2

Can Left anterior fascicular block can mask the presence
of inferior wall MI?

yes

3

where is the p wave usually found in an APC?

in T wave

4

Most common Underlying cause of LPFB

CAD

5

Name the abnormality: prolonged QT from ST lengthening

Hypercalcemia

6

Name the other EKG finding and lab abnormality assoc. w/ QT shortening, reversible LAFB/LPFB, QRS wide, disappearing p waves.

Peaked T
Hyperkalemia

7

Name the abnormality: prominent U, ST depression, flat T, QT prolonged, arrhythmias

Hypokalemia

8

6 things that prolong QT

Low mag
Low calcium
Myocarditis
MVP
hypothyroidism
Hypothermia

9

6 things that shorten QT

BB
dig
Hyperkalemia
Hypercalcemia
Hyperthyroidism
Hypothermia

10

in RBBB, axis is usually normal. When is it not?

if there is also LAFP or LPFB

11

in AV dissociation, is atrial rate or ventricular rate faster?

ventricular

12

name 3 things commonly seen in AIVR

ventricular capture beats, fusion beats and AV dissociation

13

when diagnosing an inferior MI, age indeterminate, what else should you look for?

posterior MI (prominent R in V1, V2)

14

criteria for low voltage on ekg

limb leads < 5mm (includes R + S)
precordial < 10mm

15

Cornell Criteria for LVH

R aVL + S III > 20mm females/ > 28mm Males

16

R wave in aVL > ? = LVH

12mm

17

R in Lead I > ? = LVH

14mm

18

R wave in aVL > ? = LVH
R in Lead I > ? = LVH

12mm
14mm

19

LVH: R wave in V5 or V6 + S wave in V1 = ?

> 35 mm if age > 40 years
> 40 mm if age 30-40 years
> 60 mm if age 16-30 years
