1
The Basics of
Synchronized Cardioversion
  • Steps and Procedures
2
Definition
  • Synchronized Cardioversion
    • A controlled form of defibrillation for patients who still have organized cardiac activity with a pulse.
3
Indications
  • Unstable -
    • Perfusing Ventricular Tachycardia
    • SVT
    • Atrial Fibrillation (with a rapid ventricular response)
    • 2:1 Atrial Flutter
4
Procedure
  • Similar to Defibrillation
  • Sedate conscious patients if at all possible
  • Press the “sync” button
  • Confirm synchronization on monitor (R wave is detected)
  • Charge to appropriate energy level.
    • Adults in SVT or A. Flutter – 50 J
    • Adults in VT or A. Fib – 100 J
    • Children 0.5 J/kg
5
Procedure (cont’d)
  • Clear patient
  • Depress the shock button and hold until countershock is delivered.
  • Evaluate patient’s ECG
6
Confirm Captured R Wave!
7
If patient doesn’t convert…
  • Press “sync” button again
  • Repeat steps of synchronized cardioversion by increasing energy as follows.
    • Adult  –> 100 J, 200 J, 300 J, 360 J.
    • Child –> 1 J/kg, 2 J/kg, 4 J/kg


  • ***  Remember to press “sync” button every time before delivering the countershock
8
It the patient goes into VF…
  • Press “sync” button to stop R wave synchronization and proceed with defibrillation at 200 J (or manufacture’s recommendations.)
9
If the patient converts to…
  • Asystole or PEA
    • Go to Pulseless Arrest Algorithm
  • Bradycardia
    • Go to Bradycardia Algorithm
  • Normal organized rhythm with a pulse
    • Monitor V/S
    • Administer antidysrhythmic loading bolus if required and maintenance IV drip
      • ie Amiodarone or Lidocaine
10
Consider sedation with…
  • Valium® (diazepam)
  • Versed® (midazolam)
  • Ativan® (lorazepam)
  • etomidate
  • ketamine
