QUESTIONS GUARANTEED TO PASS.
⩥ Idioventricular Rhythm (IVR). Answer: Impulse originates in the
ventricles
▪ Rhythm: Ventricular is usually regular
▪ Rate: Ventricular between 20-40
▪ QRS: ≥ 0.12
▪ Atrial rate, rhythm, and PRI: N/A
- Treatment: assess pt, check for DNR in chart, transcutaneous pacing,
atropine. NEVER GIVE ANTI-ARRYTHMICS MEDICATIONS
⩥ Accelerated Idioventricular Rhythm. Answer: Follows the same
criteria as IVR, except Ventricular rate is 40-100.
• If no intervention happens, the patient will deteriorate.
- Treatment: assess pt, atropine, transcutaneous pacing. NEVER GIVE
ANTI-ARRHYTHMIC MEDICATIONS
⩥ Ventricular Pacing. Answer: • The pacemaker lead is placed in to right
ventricle.
• The pacemaker generator fires an impulse Initiating ventricular
activity.
,• The right ventricle will contract first followed by the left ventricle.
This results in a wide QRS
• Atrial activity is typically absent. Therefore, Atrial rhythm, rate, and
PRI are non- measurable
• Rhythm: Ventricular regular
• Rate: Ventricular within set pacer limits. Measured from pacer spike to
pacer spike
• QRS: Wide; Pacer spike seen before each QRS. Measured from pacer
spike to end
of QRS
⩥ Atrial-ventricular Pacing. Answer: One pacemaker lead is placed into
the right atria and another is placed into the right
ventricle.
• The pacemaker generator fires an impulse to the atria and then to the
ventricle sequentially
causing atrial then ventricular contraction.
• Rhythm: Atrial and Ventricular regular
• Rate: Atrial and Ventricular same & within set limits
• P waves: Pacer spike seen at beginning of atrial activity P waves may
or may not be seen
(lead type dependent)
• PRI: WNL - Measured from atrial spike to ventricular spike
• QRS: Wide - Measured from ventricular spike to end of QRS
, ⩥ Failure to capture. Answer: A pacer spike note followed by the
appropriate atrial or ventricular response
• Can be a potentially lethal situation!
⩥ Failure to pace. Answer: Absence of pacer activity (spikes) when the
pacemaker generator should have fired an impulse.
• Typically seen when the patient's intrinsic heart rate falls less than the
pacemaker's low HR limit and
the pacer fails to fire.
⩥ 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]
⩥ Sinus Tachycardia. Answer: These rhythms follow all the criteria for
NSR except for the rate.
• Rate: Atrial and Ventricular 100-150
