Interval:The time between two specific ECG events. The intervals commonly measured on an ECG include the PR interval, QRS interval (also called QRS duration), QT interval and RR interval. Segment:The length between two specific points on an ECG that are supposed to be at the baseline amplitud...

QT interval is the time from the start of the Q wave to the end of the T wave, time taken for ventricular depolarisation and repolarisation

The morphology of this signal cannot be directly compared to a real ECG, but the changes in QT interval due to a drug can be represented. A prerequisite is to model the transmural heterogeneity properly, as already discussed in Section 2.2. One of the first studies which closed the gap ...
Due to the effects of heart rate, the corrected QT interval (QTc) is frequently used. The QTc is considered prolonged if greater than 450 ms in males and 470 ms in females. It is calculated using Bezett’s formula, described below. ...
