🔴⏬Recurrent Polymorphic VT/Torsades de Pointes - Management Algorithm⤵️
🔹First line: magnesium sulfate
• Adult load: 2-4 gm over 10-15 minutes
• Adult infusion after load: 0.5-1 gm/hour
• Pediatric load: 25-50 mg/kg over 10-15 minutes
🔹First line: magnesium sulfate
• Adult load: 2-4 gm over 10-15 minutes
• Adult infusion after load: 0.5-1 gm/hour
• Pediatric load: 25-50 mg/kg over 10-15 minutes
🔹Increasing chronotropy (goal 90-110 bpm)
• Prevents future TdP. Does NOT treat current TdP
• Isoproterenol (non selective beta agonist)
• Adult: 0.5-5 mcg/min
• Pediatric: 0.1-1 mcg/min
• Overdrive pacing (transcutaneous or transvenous)
• Prevents future TdP. Does NOT treat current TdP
• Isoproterenol (non selective beta agonist)
• Adult: 0.5-5 mcg/min
• Pediatric: 0.1-1 mcg/min
• Overdrive pacing (transcutaneous or transvenous)
🔹Anti-arrhythmic
• Class 1b (lidocaine)- case report level evidence
• Load: 1-1.5 mg/kg
• Infusion: I mg/min
