Summary

The LINQ QT Study is a prospective, non-randomized, multi-center, observational, post-market clinical study investigating QT interval changes due to antiarrhythmic drug loading.

Detailed description

The purpose of this study is to determine if QT interval changes are detected during and after antiarrhythmic drug loading by the designed QT detection algorithm from LINQ ECG. The QT intervals during the anti arrhythmic loading hospitalization period will be compared for all patients to analyze QT changes that may be caused due to antiarrhythmic drugs.
