Key result
QT interval assessment effectively identifies drug-induced arrhythmia risk when using sensitive, specific measurement methods.
Why the study?
Improved understanding and measurement of QT interval changes suggest its use as a marker for drug action and arrhythmia risk requires sensitive and specific methods.
Design

May aid drug safety monitoring; leaves open standardization of precise QT methods in practice.
This review highlights the evolving role of the QT interval as a precise marker for both drug efficacy and toxicity, emphasizing the need for accurate measurement methodologies.
Woosley et al. (1993) conducted a review in QT prolongation and arrhythmia. The QT interval serves as a valuable clinical marker for detecting and quantifying the risk of drug-induced arrhythmia, necessitating sensitive and specific measurement methodologies.
