Classification:
Antidysrhythmic (electrolyte)
(Electrolyte, which has antidysrhythmic properties if ectopy is due to hypomagnesemia)
Indications:
• Refractory ventricular dysrhythmias, Torsades de Pointes, hypomagnesemia
Actions:
• Stabilizes tissue membranes (including myocardial cells), elevates Magnesium levels
Dosage:
• Refractory VF or pulseless VT (if potentially Torsades ): 1 – 2gm IV push
• Hypomagnesemia without ectopy: 0.5 – 1gm/hr infusion
Route:
• IV Push or IV infusion
Side effects:
• Mild bradycardia, hypotension
Caution:
• Overdosage: diarrhea, paralysis, circulatory collapse
