Flashcards in ECG stuff Deck (34):
1

Lateral Infarct Q waves

I, AvL, V5, V6

2

abnormal septal depolarization

Absent Q waves in aVL and I

3

What is irregularly irregular?

A fibrilation

4

MI axis deviation

away from MI

5

Progression of transmural injury

Peaked T, T wave inversion, ST elevtion, Q wave

6

hypercalcemia

short QT

7

Torsades de pointes

v tach

8

T peaks

Hyperkalemia

9

Normal septal depolarization

Q waves in avL, I, V6

10

Hypocalmeai

U wave (flattening of T)

11

Hypertrophy axis deviation

towards axis

12

LBBB

abnormal septal depolarization QRS > 0.12 sec V1 and V2 with wide S V5 and V6 with RSR'

13

which have absent P waves?

Atrial fibrillation, junctional rhythm, V tac and fib, premature ventricular contraction

14

Hyperkalemia

T peak

15

Diffuse ST elevation

pericarditis

16

LPFB

RAD, R1Q3 down up up

17

T wave inversion

ischemia in low o2 demand

18

RVH is

increase R wave in V1 and V2

19

Atrial Hypertrophy Right

Peaked T waves in I, II, or III Biphasic P wave in V1

20

hypocalcemia

long QT

21

Ischemia

Alt. Ventricular repolarizattion - ST segment despression and T waves. St depression: ischemia in high oxygen demain (coronary insufficiency) T wave inversion: due to acute a. obstruction in low O2 demand.

22

ST elevation

transmural injury

23

Anterior Infarct Q waves

V1, V2, V3, V4

24

Inferior infarct Q waves

II, III, aVF

25

LVH is

increased R waves in I, aVL, V5 and V6 or >11 in aVL, >12 in I, and >10 in aVF

26

RBBB

Normal Septal Depolarization QRS>0.12 sec RSR' or M shape in V1 and V2 Slurred S in I, aVL, V5, V6

27

LAFB

LAD Q1R3 Up, down, down, with RBBB

28

Q waves

necrosis; significant if >0.4 wide or 1/4 height of QRS

29

what has no QRS

V fibrillation, asystole

30

Left Atrial Hypertrophy

But shape in I, II, or III Bisphasic P wave in V1

31

ST depression

ischemia in high oxygen demand or subendocardial injury

32

what is the trick for BBB?

go to J point and think turn signal

33

Transmural injury

ST elevation

34

Posterior Infarction

ST depression in V1 and V2 Tall R, no Q
