Flashcards in EKG exam 1 images Deck (43):
1

Axis?

Left axis deviation 

Lead I=Positive

aFV=Negative

2

Axis?

Extreme right axis deviation 

Lead I=negative

aVF=negative

3

Pathologic Q-waves?

Yes. ≥1/3 height of R-wave

4

R wave progression?

Abnormal R wave progression in precordial V leads

5

T waves

T waves inverted in V2, V3, III
 

6

Rate? Regular or Irregular rhythm?

~85bpm. Basically regular (sinus arrhythmia).

7

Axis? QRS complexes (narrow vs. wide)? Intervals (PR interval, QT interval)?

Axis=Narrow

QRS-Complex=Normal

Intervals=Normal

8

P-waves? Q-waves? T-waves? Normal R-wave progression?

P waves are present, normal morphology, precedes
QRS complexes.

Normal R wave progression.

T-waves=Mostly upgoing, flat in lead III

Q-waves=Pathologic Q waves in lead III 

9

PR-seg, ST-segment elevated, depressed or normal?

PR and ST segments are normal 

10

Overall interpretation?

Normal Sinus Rhythm at a rate of 85bpm with pathologic Q waves and inverted T waves in lead III
 

11

Rate, rhythm (reg or irreg), axis?

~70bpm, Regular rhythm
Axis=left axis deviation (Lead I up, aVF down)

12

QRS complexes narrow or wide? PR-int and QT-int normal?

QRS=normal

PR and QT intervals normal 

13

P-waves? Q-waves? T-waves? Normal R-wave progression?

P waves are present. They are wide and double humped. P waves precede QRS complexes.

QS waves in lead III & V2 

T-waves=Mostly upgoing, slightly flattened in Lead III

Poor R wave progression 

14

PR and ST segments? ( elevated, depressed or normal)

PR and ST segments are normal 

15

Overall interpretation?

 Normal sinus rhythm at a rate of 70bpm with left atrial enlargement, left axis deviation, and poor R wave progression
 

16

Rate? Rhythm (reg or irreg)? Axis?

Rate=~95bpm 

Rhythm=Regular

Axis=Extreme right axis deviation

17

P-waves? Q-waves? T-waves? Normal R-wave progression?

P waves are present, tall in amplitude. P waves
precede QRS complexes 

Pathologic Q waves in Lead III 

T waves inverted in V2, V3, III
Abnormal R wave progression 

18

PR and ST segments elevated, depressed, or normal

PR and ST segments are normal 

19

Overall interpretation?

Normal sinus rhythm at a rate of 95bpm with evidence of right ventricular hypertrophy and right atrial enlargement.
 

20

Normal or abnormal P-wave? What does it mean?

R ATRIAL ENLARGEMENT

21
