Question	Answer
Treatments for Torsades de pointes?	Magnesium, Isoproterenol, Overdrive pacing, Defibrillation
Most specific sign in acute CHF?	S3
Joules for synchronized cardioversion? (with biphasic)	Narrow regular(eg SVT: 50-100 J Narrow irregular (eg A fib): 120-200 J (50-100 J often sufficient for A flutter) Wide regular (eg Vtach): 100 J
Joules for defibrillation?	120-200 J
Most common cause of pacemaker failure to pace?	Oversensing
EKG findings in pericarditis?	Diffuse PR depressions and ST elevations (reversed in aVR)

Question	Answer
Lab findings and treatment for ethanol toxicity?	+ osmolar gap, + anion gap (if ketoacidosis), supportive care
Lab findings and treatment for methanol toxicity?	+ osmolar, + anion gap, fomepizole, thiamine, pyridoxine, +/- dialysis
Lab findings and treatment for ethylene glycol toxicity?	+ osmolar, + anion gap, fomepizole, folinic acid, +/- dialysis
Lab findings and treatment for isopropyl alcohol toxicity?	+ osmolar gap, - anion gap, supportive care
