Flashcards in ECG, CT Deck (11):
1

Give appearance of extradural, subdural, subarachnoid, intracerebral

extradural - concave shape
subdural - crescent shape
subarachnoid - blood in ventricles or inbetween gyri
intracerebral - occurs in brain tissue

2

how long is 1 small box on ecg

200 ms

3

draw positions of where leads look at heart

see book

4

What would cause right and left axis deviation

right - pulmonary embolus (RVH)
left - conduction defect, LVH

5

how does WPW and heart block affect PR interval

WPW shortens
heart block lengthens

6

hyperkalemia on ecg

tall tented T waves, widened QRS, P wave flattens

7

hypokalaemia on ecg

stunted T waves, U wave, ST depression

8

NSTEMI ecg

ST-segment depression, T-wave inversion.

9

STEMI ECG

ST elevation, Q waves, T wave inversion

10

What would u see on ventricular ectopic beats ECG

QRS being wider and taller every other beat or 3rd beat etc.

11

Explain ecg findings on 1st degree, type 1 and 2 2nd, 3rd degree heart block

1st degree - PR longer
Type 1 2nd - PR elongates until QRS dropped
type 2 2nd - PR normal but QRS sometimes dropped
type 3 - P waves and QRS have no relationship.
