EKG exam 1 images Flashcards
Axis?
Left axis deviation
Lead I=Positive
aFV=Negative
Axis?
Extreme right axis deviation
Lead I=negative
aVF=negative
Pathologic Q-waves?
Yes. ≥1/3 height of R-wave
R wave progression?
Abnormal R wave progression in precordial V leads
T waves
T waves inverted in V2, V3, III
Rate? Regular or Irregular rhythm?
~85bpm. Basically regular (sinus arrhythmia).
Axis? QRS complexes (narrow vs. wide)? Intervals (PR interval, QT interval)?
Axis=Narrow
QRS-Complex=Normal
Intervals=Normal
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
PR-seg, ST-segment elevated, depressed or normal?
PR and ST segments are normal
Overall interpretation?
Normal Sinus Rhythm at a rate of 85bpm with pathologic Q waves and inverted T waves in lead III
Rate, rhythm (reg or irreg), axis?
~70bpm, Regular rhythm
Axis=left axis deviation (Lead I up, aVF down)
QRS complexes narrow or wide? PR-int and QT-int normal?
QRS=normal
PR and QT intervals normal
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
PR and ST segments? ( elevated, depressed or normal)
PR and ST segments are normal
Overall interpretation?
Normal sinus rhythm at a rate of 70bpm with left atrial enlargement, left axis deviation, and poor R wave progression
Rate? Rhythm (reg or irreg)? Axis?
Rate=~95bpm
Rhythm=Regular
Axis=Extreme right axis deviation
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
PR and ST segments elevated, depressed, or normal
PR and ST segments are normal
Overall interpretation?
Normal sinus rhythm at a rate of 95bpm with evidence of right ventricular hypertrophy and right atrial enlargement.
Normal or abnormal P-wave? What does it mean?
R ATRIAL ENLARGEMENT
Normal or abnormal P-wave? What does it mean?
LEFT ATRIAL ENLARGEMENT. Notched P-wave.
Normal or abnormal P-wave? What does it mean?
Left atrial enlargement
Normal or abnormal P-wave? What does it mean?
LEFT ATRIAL ENLARGEMENT
What sort of enlargement?
BIATRIAL ENLARGEMENT
Pathologic Q-waves due to MI where?
Inferior MI
Which are pathologic Q, which is normal?
Pathologic=III and aVF
Normal=aVR
Normal or not?
Narrow is normal! >0.1sec is considered a wide QRS complex.
Normal or wide QRS-complex?
Wide!
Normal or wide QRS-complex?
Wide!
