Interventions

LINQ/LINQ IIdevice

Algorithm developed and validated to continuously measure QT intervals for every beat using LINQ/LINQ II ECG. This study is aimed at determining if QT interval changes can be detected during antiarrhythmic drug loading by the designed QT detection algorithm from LINQ/LINQ II ECG.
