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 before and after antiarrhythmic loading will be compared for all patients to analyze QT changes that may be caused due to antiarrhythmic drugs.
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.
