1

What type of rhythm is this?

 

Sinus arrhythmia = non-pathological variation with respiration = looks irregular in bunches

 

2

What type of rhythm is this?

premature atrial contraction = early QRS complex originated by abnormal P wave followed by compensatory pause; but QRS complex itself looks normal

3

What type of rhythm is this?

premature ventricular contraction

4

Is this sinus rhythm? What is it?

No! because P waves present and regular but not upright in I/II

since P wave = problem is not with atria,
must be problem with where focus is [atrial rhythm/tachycardia with focus coming from somewhere else], or heart just not where its supposed to be [dextrocardia] OR you put leads in the wrong dir [inverted right and left]

5

What causes this rhythm?

 

dextrocardia

 

inverted P wave in I, decreasing amplitude from V1 to V6 [opposite what you’d expect = muscle mass decreasing toward left]

6

What causes this rhythm?

p wave inverted 1, 2 but normal progression of QRS so unlikely to be dextrocardia

III + aVF = good; aVL should have been upright but its not; aVR should have been negative but its not

--> you accidentally switched L and R 

7

Sinus or non-sinus? Normal, brady, or tachy?

sinus bradycardia

8

What rate? Sinus or non? Normal brady or tachy?

sinus tachycardia

9

What axis?

right axis deviation à V1 negative, AVF positive

10

What axis?

 

left axis deviation à V1 positive, AVF negative

11

What axis?

left axis deviation

12

What causes this type of axis?

left anterior fascicular block

13

What causes this?

left bundle branch block = broad QRS, looking down in V1

14

What causes this?

right bundle branch block = broad QRS, looking up in V1

15

What causes this?

right bundle branch block = broad QRS, looking up in V1

16

What causes this?

left bundle branch block = broad QRS, looking down in V1

17

What rhythm is this?

right BBB à broad QRS, rabbit ears, upright V1

18

What rhythm is this?

WPW à short PR, delta wave on upstroke of QRS, broad QRS

19

What rhythm is this?

posterior wall infarct --> huge positive R in V1, prominent Q waves in leads II and III [inferior leads]

20

What rhythm?

LVH

21

What rhythm?

RVH with right axis deviation

22

What rhythm is this?

Wolf parkinson white = WPW

23

What rhythm is this?

wolf parkinson white = WPW

24

What rhythm is this?

Wolf Parkinson White = WPW

25

What rhythm is this?

Right bundle branch block

26

What does this rhythm suggest?

posterior infarct

27

What does this rhythm suggest?

left ventricular hypertrophy

28

What does this rhythm suggest?

right ventricular hypertrophy

29

Which leads correspond to inferior wall? septal wall? anterior wall? anteroseptal wall? lateral wall?

inferior = leads II, III, aVF

septal = V1 and V2

anterior = V3 and V4

anteroseptal = V1, V2, V3, V4

lateral = I, aVL, V5, V6 [I/aVL = high lateral; V5/V6 = anterolateral]

30

What does this rhythm show?

diffuse subendocardial ischemia = ST depressions and T wave inversions
