EKG Test HCA UPDATED ACTUAL Questions and CORRECT Answers
1. normal sinus HR 60-100 bpm
rhythm Regular
2. Sinus Bradycar- HR <60 bpm
dia Regular
3. Sinus Tachycar- HR > 100 bpm
dia Regular
4. sinus dysrhyth- HR 60-100 bpm
mia Irregular rhythm
P waves normal
QRS complexes normal
PR Intervals normal
5. Sinus Arrest HR 60-100 bpm
Rhythm is irregular where there is a pause
P waves, QRS complexes and PR intervals are normal and all look alike (but absent
where there is a pause in rhythm)
6. Wandering Atrial -HR 60-100 bpm
Pacemaker -Slightly irregular
-P waves differ, as frequently as from beat to beat, may be upright or inverted, can
even be absent
-QRS complexes normal, all appear the same
-PR intervals vary, when the P wave is present the P'R intervals may be normal,
shortened, or prolonged
-QT intervals within normal range but may vary
7. Premature Atrial -Rate depends on underlying rhythm
Complexes -Irregular due to early beat
-P' wave may be upright or inverted, will appear different than those of the
underlying rhythm

, EKG Test HCA UPDATED ACTUAL Questions and CORRECT Answers
-QRS complexes are normal
-PR intervals can be normal, shorter than 0.12 seconds in duration or prolonged
-QT intervals within normal range but may be shortened
8. Bigeminal Pre- Every other beat
mature atrial
complex
9. Trigeminal Every third beat
10. Quadrigeminal Every fourth beat
11. Atrial Tachycardia -HR 150-250 bpm
(SVT) -Regular unless the onset is witnessed (thereby producing paroxysmal irregulari-
ty)
-P' waves may be upright or inverted, will appear different than those of the
underlying rhythm, can be hidden in the preceding T wave
-QRS normal
-PR intervals can be normal, shorter than 0.12 seconds in duration or unmeasur-
able if the P wave can't be distinguished from the preceding T wave
12. Atrial Flutter -Ventricular rate may be slow, normal, or fast; atrial rate is between 250 and 350
beats per minute
-May be regular or irregular
-P waves absent, instead there are flutter waves
-QRS complexes are normal
-PR intervals unmeasurable
13. Atrial Fibrillation -Ventricular rate may be slow, normal, or fast; atrial rate is greater than 350 bpm
(F waves) -Totally irregular
-P waves absent, instead there is a chaotic-looking baseline
-PR intervals unmeasurable
