Overview
Common causes for torsades de pointes include hypomagnesemia and hypokalemia. It is commonly seen in malnourished individuals and chronic alcoholics. Drug interactions such as erythromycin or Avelox, taken concomitantly with inhibitors like nitroimidazole, diarrhea, dietary supplements, and various medications like methadone, lithium, tricyclic antidepressants or phenothiazines may also contribute to causing torsades de pointes.
