Chapter 4 EKG quiz

The presenting problem with Sinus Bradycardia is that:
-the rate is too slow
-the P waves are irregular
-the PRI is too long
-the QRS is too wide

the rate is too slow

For Sinus Tachycardia, the QRS complex should be less than ________ sec.
-0.18
-0.12
-0.01
-0.20

0.12

The term "tachycardia" means:
-slow heart
-sinus rhythm
-normal heart
-fast heart

fast heart

The rate for Sinus Bradycardia is ________ bpm.
-more than 100
-equal to 100
-between 60-100
-less than 60

less than 60

In Sinus Arrhythmia, the rate changes with the patient's:
-pulse
-respirations
-AV node
-SA node

respirations

In Normal Sinus Rhythm, the heart rate is ________ bpm.
-80-120
-60-100
-100-120
-40-60

60-100

For all rhythms that originate in the sinus node, you would expect all of the following EXCEPT:
-one P wave for every QRS complex
-PRI measurement between 0.12-0.20 sec
-inverted P waves following the QRS complexes
-PRIs constant across the entire strip

inverted P waves following the QRS complexes

The presenting problem with Sinus Tachycardia is that:
-the rate is too fast
-the QRS is too narrow
-the PRI is not constant
-the rhythm is irregular

the rate is too fast

The rate for sinus Tachycardia is ________ bpm.
-60-100
-less than 60
-greater than 100
-less than 80

greater than 100

In Sinus Arrhythmia, the R-R intervals are:

-normal
-increasingly delayed

irregular

In Sinus Arrhythmia, the heart rate is usually ________ bpm.
-greater than 100
-less than 60
-60-100
-less than 80

60-100

A Normal Sinus Rhythm has all of the following characteristics EXCEPT:
-the R-R intervals vary
-heart rate is normal
-QRS is less than 0.12 sec

the R-R intervals vary

The presenting problem with Sinus Arrhythmia is that:
-the QRS is too wide
-the rhythm is irregular
-the PRI varies from beat to beat
-the PRI is too long

the rhythm is irregular

When a sinus rhythm has a QRS complex of 0.12 sec. or greater, you know that this is an abnormality and would note that it has:
-sinus conduction defect

-inverted or flattened
-characteristically peaked
-biphasic or notched

upright and uniform
