Arrhythmia Risk Stratification based on QT Interval Instability

摘要

BackgroundExperimental studies have demonstrated that unstable repolarization dynamics is a risk factor of arrhythmia. We have recently developed an algorithm to detect QT interval (QTI) instability from the clinical ECG. In this study we developed a clinical arrhythmia risk stratification index based on the detection of QTI instability.
