Advent Health EKG ( 2026/2027 Update)
Questions and Answers with Diagrams and Illustrations
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
