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:
-constant
-irregular
-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
-P waves are uniform
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
-accelerated ventricular conduction
-Purkinje disease
-a wide QRS
a wide QRS
In NSR, the PR interval must fall between ________ sec.
-0.08-0.22
-0.20-0.60
-0.04-0.06
-0.12-0.20
0.12-0.20
For all rhythms that originate in the sinus node, you would expect the P wave in Lead II to be:
-upright and uniform
-inverted or flattened
-characteristically peaked
-biphasic or notched
upright and uniform
