What AHA HR = bradycardia?
“Typically <50bpm”
What are the general steps of the Bradycardia algorithm?
What is CHAAPS
CHAAPS = mnemonic to determine if pt stable or not
Chest pn, hypotension, AMS/acute heart failure, Pulm edema, shock SS
Dosage for Atropine (max dose?)
First dose = 0.5mg then repeat every 3-5min
Max dose = 3mg
What is dosage/infusion rate for dopamine IV
Dose = dale’s rule (in lbs, drop last number & minus 2)
Infusion = 2-20mcg/kg per min. Titrate to effect
Dosage/infusion rate for IV epi (bradycardia)
2-10 mcg per min. Titrate to effect
What AHA HR = tachyARRHYTHMIA (SVT)
150bpm or more (SVT)
General steps of Tachy (SVT) algorithm
Rx for tachyarrhythma (SVT) w/ CHAAPS
Synchronized cardioversion.
Consider: sedation or adenosine (if narrow complex SVT)
Rx for stable, wide complex QRS SVT
Rx for narrow complex QRS SVT (no CHAAPS)
You want to cardiovert your SVT pt. what initial joules for wide regular SVT vs wide irregular SVT?
Wide regular = 100 J
Wide irregular = no cardiovert. Defibrillation
You want to cardiovert your SVT pt. What initial Joules for the following:
Narrow regular SVT = 50-100J
Narrow irregular SVT = 120-200 J (biphasic), or 200 J (monophasic)
Biphasic vs monophasic shock pads?
Biphasic = current goes from one pad to the other then back
Monophasic = current goes from one pad to the other
For tacharrhythmias (SVT), what dose for adenosine?
1st = 6mg rapid IVP, follow w/ flush
2nd = 12mg if needed
3rd = 12mg ( for hospital, call MCP)
What Rx for stable, wide QRS complex SVT?
Rx = Procainamide, amiodarone, Sotalol
If unsure if SVT vs VTach. Assume Vtach and defib
What is Procainamide? indications & contraindications?
Procainamide = antiarrhythmic infusion med
Indication = stable wide QRS complex tachycardia (SVT)
Contraindication = prolonged QT or Hx CHF
Procainamide:
Infusion dose/rate?
Maintenance rate?
Max dose?
Dose/rate = 20-50mg/min
Maintenance = 1-4 mg/min
Max dose/stop = arrhythmia suppressed, pt hypotensive, QRS duration >50%, or max dose 17mg/kg given
What is amiodarone? When to use it?
Amiodarone = antiarrhythmic infusion med For stable, wide QRS tachyarrhythmia (SVT)
Also used for cardiac arrest w/ vfib or pulseless vtach
Amiodarone initial infusion rate? Maintenance infusion rate?
Initial = 150mg over 10 min. Repeat PRN if Vtach recurs. Follow w/ maintenance infusion
Maintenance infusion = 1mg/min for first 6 hours
What is Sotalol? What contraindications?
Sotalol = Antiarrhythmic infusion med for stable, wide QRS tachycardia
Contraindications = prolonged QT
What is the dosage for Sotalol?
100mg (1.5mg/kg) over 5 min
