Arrhythmia and Pacemakers

The SA node fires at a rate of

• 20 - 40 bpm

• 40 - 60 bpm

• 60 - 100 bpm

• 50 - 70 bpm

Identify the rhythm

• sinus bradycardia

• first degree AV block

• 2nd degree AV block

• 3rd degree AV block

Appropriate treatment for this type of rhythm is

• Atropine 0.5 mg IV

• Epinephrine 1: 10,000 mg IV

• CPR

• Transcutaneous pacing

The AV node fires at a rate of

• 20 - 40 bpm

• 40 - 60 bpm

• 60 - 100 bpm

• None of the above

The 1st A in AAI means

• atrial sensed

• atrial paced

• pacer in inhibited when atrial activity is detected

• pacer is triggered when atrial activity is detected

The I in VVI means

• Ventricle is paced when no intrinsic activity is detected

• Pacing is inhibited when ventricular activity is detected

• Pacing is inhibited when atrial activity is detected

• Ventricle is paced when atrial activity is detected

Identify the rhythm

• Atrial paced

• Ventricular paced

• AV paced

• Normal sinus rhythm

Identify the rhythm

• Atrial paced

• Ventricle paced

• AV paced

• Ventricular tachycardia

Identify the rhythm

• Atrial paced

• Ventricle paced

• AV paced

• Ventricular tachycardia

The pacemaker is

• working normally

• undersensing

• oversensing

• not capturing
