Treat like paroxysmal SVT
Unstable
Cardioversion (synchronized)
Adult: 50-100 J
Peds: 0.5-2 J/kg
Stable
Calcium channel blockers, beta-blockers, procainamide, or adenosine
Procainamide is safest, as safe irrespective of type of pathway conduction
Cardioversion (synchronized)
Adult: 50-100 J
Peds: 0.5-2 J/kg
Calcium channel blockers, beta-blockers, procainamide, or adenosine
Procainamide is safest, as safe irrespective of type of pathway conduction
Treat like ventricular tachycardia
Synchronized cardioversion
Adult: 50-100 J
Peds: 0.5-2 J/kg
Procainamide (see page for dosing guidelines)
Avoid if prolong QT or CHF
Amiodarone with 'ABCD' drugs ie adenosine, beta-blockers, calcium-channel blockers, digoxin
Wide-complex, irregular (presumed preexcited A-fib)
Unsynchronized cardioversion (200J)
Adult: 50-100 J
Peds: 0.5-2 J/kg
Procainamide (see page for dosing guidelines)
Avoid if prolong QT or CHF
Amiodarone with 'ABCD' drugs ie adenosine, beta-blockers, calcium-channel blockers, digoxin
Avoid if prolong QT or CHF
Unsynchronized cardioversion (200J)
Stable
Procainamide 20-50 mg/min until arrhythmia suppressed
Synchronized cardioversion, 100 - 200 J
Unstable - synchronized cardioversion
Consider higher joule dosage and frequency of repeats than for stable
Avoid AV nodal blocking agents
Procainamide 20-50 mg/min until arrhythmia suppressed
Synchronized cardioversion, 100 - 200 J
Consider higher joule dosage and frequency of repeats than for stable
Wolff–Parkinson–White syndrome
Regular
Wernicke-Korsakoff syndrome
AV Node Independent
Vaughn Jackson syndrome
Sinus tachycardia
Sydenham's chorea
Atrial tachycardia
