What initial interventions are essential for any adult patient presenting with a wide complex tachycardia?
- Prepare immediately for synchronized cardioversion

Study Notes
-
General adult assessment should include cardiac monitoring, vascular access, and a 12-lead ECG
-
If the ECG shows a wide complex of > 0.12 seconds, this is a wide complex tachycardia
-
Wide complex tachycardia may present as:
- Undifferentiated monomorphic VT
- Suspected SVT with aberrancy
- Regular monomorphic VT
- Torsades de Pointes
-
Treat regular monomorphic VT with amiodarone 150mg in 50ml NS over 10 minutes
-
Treat Torsades de Pointes with Magnesium Sulfate 2gm IV/IO in 50ml NS over 10 minutes
-
If the administration of amiodarone for regular monomorphic VT is unsuccessful, perform synchronized cardioversion with consideration of sedation and analgesia; medications and dosages are referenced from the Electrical Therapy/Synchronized Cardioversion Procedure Protocol
-
If the administration of Magnesium Sulfate to treat Torsades de Pointes is unsuccessful, perform defibrillation with consideration of sedation using etomidate 0.15mg/kg IV/IO

Description
This lesson covers the treatment of wide complex tachycardia. It discusses differentiation and treatment with amiodarone or magnesium sulfate, and when to escalate care to synchronized cardioversion or defibrillation. Specific medications and dosages are included.
