1 .		When checking the heart rate on a six second strip, counting the R waves represent: [Hint]   Contractions of the heart   Atrial and ventricular heart rate   Atrial heart rate   Ventricular heart rate
2 .		The term tachycardia means the heart rate is: [Hint]   Greater than 100 beats per minute   Less than 100 beats per minute   Greater than 60 beats per minute   Less than 60 beats per minute
3 .		The term bradycardia means the heart rate is: [Hint]   Greater than 100 beats per minute   Less than 100 Beats per minute   Greater than 60 beats per minute   Less than 60 beats per minute
4 .		When the term “ irregularly irregular “ is utilized, it means: [Hint]   Irregular rhythms occur in a pattern   R to R intervals exhibit no similarity   Intervals of only one or two R-Rs are uneven   R to R are off by 0.06 seconds
5 .		Normal PR interval is: [Hint]   Less than 0.12 sec.   Greater than 0.20 sec.   0.12 to 0.20 sec.   0.10 to 0.22 sec.
6 .		The normal QRS complex will measure: [Hint]   Greater than 0.12 sec   Less than 0.10 sec   0.12 to 0.20 sec.   Less than 0.12 sec.
7 .		QRS complexes greater than 3 small boxes indicate the rhythm is: [Hint]   Ventricular in origin   Atrial in origin   Poor electrode placement   Artifact in origin
8 .		The segment between the QRS complex and onset of the T wave is the: [Hint]   J segment   PT segment   ST segment   QT segment
9 .		The J point is utilized when looking for elevation or depression of the: [Hint]   ST segment   QT segment   PT segment   QRS segment
10 .		EKG waveforms produced from sources outside the heart and caused by patient movement, improper grounding, 60 – cycle interference are called: [Hint]   Poor deflections   F waves   U waves   Artifact
