Preferred Label : Aggregate QTca Interval;
NCIt related terms : QTCAAG; QTca Interval, Aggregate;
NCIt definition : The correction on the aggregate of QT intervals using individual probabilistic QT/RR
slopes for each subject based on the measurement of QT intervals from multiple beats
within a single ECG or from a defined time period within a continuous ECG. The method
of aggregation, which can vary, is typically a measure of central tendency, such as
mean.;
Alternative definition : CDISC: A QT Aggregate interval that is corrected for heart rate using individual probabilistic
QT/RR slopes for each subject, based on the measurement of QT intervals from multiple
beats within a single ECG or period of a continuous ECG. The method of aggregation,
which can vary, is typically a measure of central tendency such as the mean.;
