Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to assess the use of the medication ondansetron (zofran) in the emergency department. There are studies of the ability of ondansetron to cause a prolongation in the QT interval (a certain measurement on an EKG) in anesthesia and cancer patients, but not on emergency department patients. This is an observational study where patients that are going to receive the anti-nausea medicine ondansetron in the emergency department will have an EKG performed every 2 minutes for 20 minutes to determine if the QT interval prolongs and returns to normal in that time period. Any serious outcomes will be reported. There is expected to be no adverse outcomes from this routinely used medication.
