Perioperative torsade de pointes: a systematic review of published case reports.

Background Torsade de pointes is a rare, but potentially fatal arrhythmia. More than 40 cases of perioperative torsade de pointes have been reported in the literature; however, the current evidence regarding this complication is very limited. To improve our understanding we performed a systematic review and meta-analysis of all published case reports of perioperative torsade de pointes.
