Afib The impulse originates in the Atria
• The Atrial rate is > 300 and unable to measure
[N/A]
• 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
controlled A-fib;
if the Ventricular rate is > 100 the rhythm is
uncontrolled A-fib
• This is a chronic rhythm for some patients
Treatment: controlled patients: anticoagulants
and antiarrythmics; uncontrolled but stable
patients: Beta blockers, calcium channel blockers,
or digoxin; Unstable patients: cardioversion
,Junctional Rhythm Impulse starts in the AV junction
• P waves are absent, short, inverted or
retrograde
• Ventricular Rhythm: Regular
• Ventricular Rate: 40-60 bpm
• QRS is usually within normal limits
Accelerated Junctional Rhythm Accelerated Junctional
Same criteria as Junctional Rhythm, except the
Ventricular rate is 60-100
For stable patients: IV access, vagal maneuvers,
adenosine, O2, Beta blockers, calcium channel
blockers
Idioventricular Rhythm (IVR) 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 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 • 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
