WIDE- [QRS] COMPLEX TACHYCARDIAS

I. Differentiating VTach from SVT w/aberrant conduction: see "Electrocardiography"

II. Management:

1. Gauge sx
2. Consider vagal maneuvers
3. Can give adenosine in ?increasing doses (6mg, 12mg, 18mg)
4. Further Tx if sure of which WCT it is:

1. SVT===>Propanolol, Verapamil
2. VT====>Lidocaine (if hemodynamically stable), Defibrillation

5. If unsure which type of WCT it is,

1. If hemodynamically stable, IV Procaine (caution--will decrease BP)
2. If hemodynamically unstable, SHOCK in sync with QRS
