FIRE: Focused Initial Rapid Evaluation

A Focused Initial Rapid Evaluation (FIRE) should be performed to identify patients in need of immediate intervention.

Evaluate and treat instability:
 
 
 
 
 
Pulseless VT or PEA
 
 
 
 
 
 
 
 

❑  12-lead ECG, don't delay therapy
❑  IV/IO access
❑  Ventilation
❑  Supplementary oxygen if hypoxemic
❑  Check heart rate and blood pressure
❑  Check signs of end-organ hypoperfusion

❑  Altered mental status
❑  Cold extremities
❑  Cyanosis
❑  Oliguria (urine output <0.5 mL/kg/h)
❑  Sustained hypotension (≥30 min)
❑  SBP <90 mm Hg or
❑  MAP ↓ >30 mm Hg below baseline
❑  Ischemic chest discomfort
❑  Acute heart failure

Check duration of QRS
 
 
 
 
 
Synchronized cardioversion:
Consider sedation
If regular narrow complex, consider adenosine
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Wide complex tachycardia (≥120 ms)
 
 
 
 
 
Narrow complex tachycardia (<120 ms)
 

❑  Doses/details of synchronized cardioversion:

❑  Narrow regular: 50-100 Joule
❑  Narrow irregular: 120-200 Joule biphasic or 200 Joule monophasic
❑  Wide regular 100 Joule
❑  Wide irregular: defibrillation dose (Not synchronized)

❑  Adenosine IV dose:

❑  First dose: 6mg rapid IV push; follow with NS flush
❑  Second dose: 12mg if required
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Consider expert consultation
Consider antiarrhythmic infusion
Consider adenosine only if monomorphic and regular
 
 
 
 
 
Vagal maneuvers
Beta-Blockers or calcium channel blocker
Consider expert consultation
Adenosine if regular

❑  Antiarrhythmic infusion for stable wide-QRS tachycardia:

❑  Procainamide IV Dose:
❑  20-50mg/min until:
❑  Arrhythmia suppressed
❑  Hypotension ensues
❑  QRS duration increases 50%
❑  Maximum dose 17mg/kg given.
❑  Maintenance infusion: 1-4 mg/min.
❑  Avoid if prolonged QT or CHF.
❑  Amiodarone IV Dose:
❑  First dose: 150mg over 10 minutes. Repeat as needed if VT recurs.
❑  Follow by maintenance infusion by 1mg/min for first 6 hours.
❑  Sotalol IV Dose:
❑  100mg (1.5mg/kg) over 5 minutes.
❑  Avoid if prolonged QT.
