Antipsychotics for delirium in ICU did not result in QTc interval prolongation

Hospitalized patients receiving haloperidol or ziprasidone for delirium while in intensive care experienced no increased risk of QTc interval prolongation relative to placebo, a secondary analysis of a randomized trial has found. None of the small number of cardiac events experienced by patients receiving one of the antipsychotics were determined to be associated with study drug administration.
