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>

> 100 it is uncontrolled Atrial flutter
