Background
- Only intervene if pt is symptomatic (hypotension, AMS, chest pain, pulm edema)
Categories
- Sinus node dysfunction
- Sinus bradycardia
- Sinus arrest
- Tachy-brady syndrome (sick sinus)
- Chronotropic incompetence
- AV node dysfunction
- 1st degree AV block
- 2nd degree AV block Mobitz I/Wenckebach
- 2nd degree AV block Mobitz II
- 3rd degree AV block (complete heart block)
Treatment
- Transcutaneous pacing
- Chronotropes
- Dopamine 2-10mcg/kg/min
- Epinephrine 2-10mcg/min
- Atropine
- Can be used as temporizing measure (while awaiting pacing and/or chronotropes)
- Use cautiously in pts w/ ongoing ischemia (tachycardia may worsen ischemia)
- 0.5mg q3-5min
- Transvenous pacing
- Required if transcutaneous pacing + chronotropes is ineffective
