title: In-hospital monitoring of T-wave alternans in a case of amiodarone-induced torsade de pointes: clinical and methodologic insights.
abstract: We report a case of macroscopic T-wave alternans occurring 30 min before the onset of amiodarone-induced torsade de pointes, illustrating a means to monitor for proarrhythmia.
