Amiodarone--avoid the danger of torsade de pointes.

We present two patients who had life-threatening arrhythmias, which are highly likely to be secondary to amiodarone. This class III anti-arrhythmic is commonly prescribed for the acute presentation of supra-ventricular and ventricular arrhythmias. However, occasionally its use can transform arrhythmias from benign to dangerous. These cases highlight the need for careful attention to the indications, cautions and contra-indications of amiodarone as well as the need for vigilance following initiation of anti-arrhythmic therapy.
