Answer

The electrolyte disturbances that have been reported to precipitate torsade include hypokalemia and hypomagnesemia. These disturbances cause a delay in phase III (ie, reprolongation) and form the substrate for emergence of the dysrhythmia. Close observation is required in predisposed patients, such as those with cirrhosis or hypothyroidism.
