Title: Using the QTcI in Clinical Trials
Live Webcast: January 29, 2013 11:00 AM - 12:00 AM EST
To compensate for the heart rate effects on the QT-interval, a so-called “correction factor” is used. While there are many to choose from, regulatory agencies tend to favor the Fridericia’s correction (QTcF). In some instances, the QTcF is not appropriate. When this happens, an individual correction formula (QTcI) can be calculated. In this Webinar, we will discuss the use of correction formulae, including the purpose and use of different correction formulae.
- What are QT correction formulae
- How to choose a correction formula
- What is the QTcI
- Calculation methods for the QTcI
- Validation QT correction methods
