J Electrocardiol. 2018 Jan-Feb;51(1):108-110. doi: 10.1016/j.jelectrocard.2017.09.006. Epub 2017 Sep 27.

Abstract

We present the case of a 62-year-old woman with levofloxacin-induced Torsade de Pointes, in whom microvolt T-wave alternans was measured during acute hospitalization and when QT interval was dynamically changing, illustrating a means for monitoring proarrhythmia.

Keywords: Drug-induced; Long QT syndrome; Microvolt T-wave alternans; Torsade de Pointes.
