Questions and Verified Answers with Diagrams and Illustrations| 100% Correct
Q: normal sinus rhythm (NSR)
Answer:
Impulse starts in the SA Node

• Rate: Atrial & Ventricular 60-100 [WNL]
• Rhythm: Atrial and Ventricular are regular
• P waves: Normal; each followed by QRS
• PRI: 0.12 – 0.20 [WNL]
• QRS: 0.04 – 0.10 [WNL]
  Q: SinusTachycardia
  Answer:
  These rhythms follow all the criteria for NSR except for the rate.
• Rate: Atrial and Ventricular 100-150
  Q: Sinus Bradycardia
  Answer:
  These rhythms follow all the criteria for NSR except for the rate.
• Rate: Atrial and Ventricular < 60
  Q: Sinus Arrythmia

Answer:

• Impulse starts in the SA Node but activity varies with respirations
• Rate: Atrial and Ventricular are 60-100, but varies (slower or faster)
• Rhythm: Atrial and Ventricular is irregular (P-P and R-R intervals are irregular)
• P waves: Normal and each is followed by a QRS
• PRI: constant and within normal limits
• QRS: within normal limits
  Q: Sinus Pause/Arrest
  Answer:
  Underlying rhythm meets criteria for a sinus rhythm [SR, SB, ST] except for the missed beat(s) or
  pause
• Underlying rhythm must first be identified!
  Q: narrow complex supraventricular tachycardia (NCSVT)
  Answer:
  Impulse originates above the ventricles
• NCSVT is an umbrella term for rhythms meeting the following criteria
  1.Regular Ventricular rhythm & rate > 150
  2.QRS: 0.04 – 0.10 [normal limits]
• P waves may be seen but are often lost in the T waves: Atrial rate, Atrial rhythm and
  PRI is non-measurable [N/A]
  Q: Atrial Flutter
  Answer:
  The impulse originates in the Atria
• The Atrial rate is 250-350 and rhythm regular
• The PRI is not measurable (N/A) – Characteristic saw-tooth wave.
• The Ventricular rhythm may be regular or irregular
• QRS within normal limits
• If the Ventricular rate is < 100 it is controlled Atrial Flutter; if the Ventricular rate is

100 it is uncontrolled Atrial flutter
