The Short QTc Is a Marker for the Development of Atrial Flutter and Atrial Fibrillation

alkiviadis.1961 shared this article with you from Inoreader The Short QTc Is a Marker for the Development of Atrial Flutter and Atrial Fibrillation Via Hindawi Publishing Corporation A short QT interval has been difficult to define, and there is debate whether it exists outside of an extremely small group of individuals with inherited channelopathies and whether it predicts cardiac arrhythmias. The objective was to identify cases with short QT and their consequences. Our hospital ECG database was screened for cases with a QTc based on the Bazett formula (QTcBZT) of less than 340 ms. The QTc was recalculated using the spline (QTcRBK) formula, which more accurately adjusts for the heart rate and identifies cases based on percentile distribution of the QT interval. The exclusion criteria were presence of bundle branch block, arrhythmias, or electronic pacemakers. An age- and sex-matched cohort was obtained from individuals with normal QT intervals with the same exclusion criteria. There we re 28 cases with a short QTc (QTcRBK  View on the web Inoreader.
