Normal Sinus Rhythm - CORRECT ANSWERS ✔✔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 ANSWERS ✔✔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 ANSWERS ✔✔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 ANSWERS |\ |\ |\ |\ |\ |\ |\ |\



✔✔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 ANSWERS ✔✔Premature |\ |\ |\ |\ |\ |\



Atrial Complex in which their is a P wave but no QRS, this
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\



is called?|\




Atrial Flutter - CORRECT ANSWERS ✔✔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 ANSWERS ✔✔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 ANSWERS |\ |\ |\ |\ |\



✔✔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] |\
