-===Defibrillation===
-Indications for defibrillation include the following:
-* [[Chest pain]]
-* [[Congestive heart failure]] ([[CHF]])
-* [[Hypotension]] with symptoms
-* [[Loss of consciousness]]
-* [[Seizure]]
-=== Acute Pharmacotherapies ===
+==[[Wide complex tachycardia overview|Overview]]==
-* '''If stable''':  (More patients than you think)
-* '''DO NOT USE''' Ca2+ Channel blocker, [[Digoxin]] or [[Adenosine]] if you don't not know the etiology of the Wide Complex Tachycardia. Ca2+ Channel blockers and Digoxin can lead to accelerated conduction down a bypass tract and [[VF]].
-* Though ACLS guidelines recommend a diagnostic trial of [[Adenosine]], it can precipitate [[VF]] in some patients with SVT. Patients who have underlying coronary disease may become ischemic from coronary steal. Rhythm can degenerate and lead to [[VF]] that cannot be resuscitated. Furthermore, some [[VT]] (esp those with structurally normal hearts) are [[adenosine]] responsive and can terminate.
-*:# Etiology Uncertain
-*:#:* [[Pronestyl]]  15mg/kg load over 30 minutes then 2-6mg/min gtt
-*:# [[Ventricular Tachycardia]] with active ischemia
-*:#:* [[Lidocaine]] 1 mg/kg q5-10 min up to 3 times then 2-6mg.min gtt
-*:#:* If unsuccessful, [[Pronestyl]] as above
-*:#:* If unsuccessful, IV [[Amiodarone]] 150-300 load over 15-20min.  30-60mg/hr gtt for total of 1gram
-*:# [[Ventricular Tachycardia]] in Setting of [[Cardiomyopathy]]
-*:#:* Skip [[Lidocaine]] and go straight to [[Pronestyl]]
-*:# Positively [[SVT]] with aberrancy
-*:#:* [[Adenosine]] 6mg rapid IV bolus in large vein. May repeat with 12mg x2.
-*:#:* [[Lopressor]] 2.5-5.0mg IV
-*:#:* [[Diltiazem]] 10-20mg bolus followed by gtt 5-20mg/hr
-*:#:* [[Verapamil]] 2.5-5.0mg bolus.
-*:#:* Avoid [[Digoxin]].  Takes too long to work and can be proarrhythmic
-*:#:* [[Pronestyl]] as above
-*:# Antidromic AVRT
-*:#:* If 100% positive [[AF]] is not underlying, can terminate with a nodal blocker
-*:#:* If unsure, [[Pronestyl]] as above
