- Analyzing a Rhythm Strip Step - by - step
Answer 1)Determine the regularity of R waves 2) Calculate the heart rate 3) Identify and examine P waves 4) Measure the PR Interval 5) Measure the QRS complex
- Sinus Rhythms and arrhythmias what are they
Answer
- Normal Sinus Rhythm
- Sinus Tachycardia
- Normal Sinus Rhythm
-Sinus Bradycardia -Sinus Arrhythmia
Answer Rhythm
Answer Regular Rate 60 - 100 P waves 1 P wave before each QRS Normal in appearance PR .12 - .20 seconds QRS < .12 seconds
- Sinus Tachycardia
Answer •Rhythm Regular • Rate 100 - 160 • P waves1 P wave before each QRS Normal in appearance • PR .12 seconds - .20 seconds • QRS < .12 seconds
- Sinus Bradycardia
Answer Rhythm
Answer Regular Rate 40 - 60 1 / 3

P waves1 P wave before each QRS Normal in appearance PR .12 seconds - .20 seconds QRS < .10 seconds
- Sinus Arrhythmia
Answer •Rhythm
Answer Irregular • Rate 60 - 100 • P waves1 P wave for each QRS Normal in appearance • PR .12 seconds - .20 seconds • QRS < .10 seconds
- Atrial Arrhythmias
Answer
- Premature Atrial Contractions (PAC)
- Atrial Tachycardia
- Atrial Flutter
- Atrial Fibrillation
- Premature Atrial Contractions (PAC)
Answer •Underlying rhythm regular Irregular with PAC • Rate Rate of underlying Rhythm • P wavesPAC P Wave is premature Abnormal in size, shape or direction May be hidden ( in previous T wave) **** P waves do not march out ***** and they don't look the same • PR .12 seconds - .20 seconds (may be prolonged • QRS < .12 seconds
- Atrial Tachycardia
Answer •Rhythm
Answer Regular 2 / 3

• Rate 140-250 • P wavesHidden in preceding T wave • PR Not measurable • QRS < .10 seconds
- Atrial Flutter
Answer •Rhythm
Answer Regular or irregular • Rate Atrial rate 250 - 400 Ventricular rate varies depending on AV node conduction • P waveAbsent Flutter waves present • PR Not measurable • QRS < .10 seconds
- Atrial Fibrillation
Answer •Very irregular
* NO PATTERN AT ALL*
• Rate Atrial rate 400 or more Ventricular rate varies depending on AV node conduciton • P waveAbsent Fibrillatory waves present • PR Not measurable • QRS < .10 seconds
- Premature Junctional Contraction(PJC)
Answer •Rhythm
Answer Underlying rhythm usually regular Irregular with PJC, sinus
• Rate Rate of underlying rhythm 60-100 • P waveP wave with PJC will be inverted May be before, during, or after QRS • PR < .10 seconds- • QRS < .10 seconds
- Premature Junctional Contraction(PJC) pr interval
Answer shorter if the p wave happen after the QRS - why because the impulse is originating in the junction,
