, Normal Sinus Rhythm - correct ans:Impulse starts in the SA Node• Rate: Atrial & Ventricular 60-100
[normal limits]• Rhythm: Atrial and Ventricular are regular• P waves: Normal; each followed by QRS•
PRI: 0.12 - 0.20 [normal limits]• QRS: 0.04 - 0.10 [normal limits]
Sinus Bradycardia - correct ans:Impulse also starts in SA Node• These rhythms follow all the criteria for
Normal sinus rhythm except for the rate.• Rate: Atrial and Ventricular < 60
Sinus Tachycardia - correct ans:Impulse also starts in SA Node• These rhythms follow all the criteria for
NSR except for the rate.Rate: Atrial and Ventricular 100-150
Premature Atrial ComplexUnderlying rhythm must first be identified!Ex. SR with a PAC - correct
ans:early P wave noted, which may appear slightly different than other P waves but PRI within normal
limits.QRS within normal limits
Nonconducted PAC - correct ans:Premature Atrial Complex in which their is a P wave but no QRS, this is
called?
Atrial Flutter - correct ans: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 (called F waves) for atrial
activity• The Ventricular rhythm may be regular or irregular• QRS within normal limits• If the
Ventricular rate is < 100 it is controlled ____ _____; if the Ventricular rate is > 100 it is uncontrolled ____
____.
Atrial Fibrillation - correct ans:unable to measure [N/A] atrial rate• No discernable P waves - PRI & Atrial
rhythm cannot be measured [N/A]• The Ventricular rhythm is irregular• QRS within normal limits• If the
Ventricular rate is > 100 the rhythm is uncontrolled _____; if the Ventricular rate is < 100 the rhythm is
controlled ______
Supraventricular Tachycardia - correct ans: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: Atrialrate, rhythm, PRI is non-
measurable [N/A]
