Rhythm Strip Interpretation
Normal Sinus Rhythm
Sinus Bradycardia
Sinus Tachycardia
Sinus Dysrhythmias
100
the wave form that represents a ventricular contraction
What is the QRS?
100
a rhythm that generates in the atria and meets all 5 criteria for a normal rhythm
Normal Sinus Rhythm
100
a sinus rhythm with a rate <60 bpm
What is sinus bradycardia?
100
an ECG rhythm that meets all 5 evaluation criteria except for a rapid heart rate
What is sinus tachycardia?
100
rhythm that is influenced by the respiratory cycle
What is sinus dysrhythmia?
200
The normal time is 0.12-0.20 seconds
What is the PR interval?
200

the amount of blood pumped from the ventricle in one contraction

What is stroke volume?

200
medication and pacemakers are the normal treatments for this condition
What is sinus bradycardia
200
the heart rate above which it is considered tachycardia
What is 100 bpm?
200
a condition in which tension on the vagus nerve causes variation in the heart rate
What is vagal tone?
300
wave form representing contraction of the atria
What is the P wave?
300
a lack of blood supply or oxygen to the cells
What is ischemia?
300
dizziness, hypotension, confusion
What are symptoms of low cardiac output?
300
the sensation of a fluttering heart or rapid heart beat
What are palpitations?
300
the rate does this in response to increased pressure in the chest cavity
What is speed up?
400
The normal time frame for this waveform is 0.06 - 0.10 seconds
What is QRS wave?
400
place where a sinus rhythm originates
What is the Sinoatrial Node (SA node)?
400
The person that should be notified immediately if signs of decreased cardiac output are seen.
What is a licensed practitioner (nurse, doctor, nurse practitioner)?
400
the most common cause of a rapid heart rate
What is exercise?
400
the rhythm that occurs when there is a pause in electrical activity and no contractions occur
What is sinus arrest
500
60 - 100 beats per minute
What is a normal heart rate?
500
measuring the small boxes between the R waves and dividing the number into 1500 will give this value
What is the ventricular heart rate?
500
the medical term meaning "slow"
What is brady?
500

What are the 5 steps for interpretation?

1. Rhythm / Regularity

2. Rate

3. P-wave morphology (shape)

4. PR Interval

5. QRS duration & morphology

500
the rhythm associated with prolonged sinus arrest
