EKG HCA UPDATED ACTUAL Questions and CORRECT Answers
1. Normal Sinus Impulse starts in the SA Node• Rate: Atrial & Ventricular 60-100 [normal limits]•
Rhythm 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]
2. Sinus Bradycar- Impulse also starts in SA Node• These rhythms follow all the criteria for Normal
dia sinus rhythm except for the rate.• Rate: Atrial and Ventricular < 60
3. Sinus Tachycar- Impulse also starts in SA Node• These rhythms follow all the criteria for NSR except
dia for the rate.Rate: Atrial and Ventricular 100-150
4. Premature Atri- early P wave noted, which may appear slightly different than other P waves but PRI
al ComplexUn- within normal limits.QRS within normal limits
derlying rhythm
must first be
identified!Ex. SR
with a PAC
5. Nonconducted Premature Atrial Complex in which their is a P wave but no QRS, this is called?
PAC
6. Atrial Flutter 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 .
7. Atrial Fibrillation 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
8. Supraventricular
Tachycardia
1/4
