Examples of QRS in a sentence
ECG characteristics, including heart rate, QRS duration, and PR, and QT intervals, will be recorded on the eCRF or loaded electronically.
Depending on the polarity, all these extrema on the ECG represented a Q, R, R’ or S wave.A search for additional components of the QRS com-T-wave: A search was performed to the right of each QRSoffset for the T-wave using a search window (SWT ) inspired by Boichat et al.
We further expanded the ability of the algorithm to determine predefined configurations of all QRS-, P-, T-.
Identification of the fiducial points was done in four parts: Finding QRS locations and identifying the largest deflection within the complexes, detection and delin- eation of individual QRS components, identification of QRSonset and QRSoffset and identification of the peaks, onsets and offsets of the P-, T- and U-waves.QRS complex: A location in the vicinity of each QRS was initially detected using a beat detection algorithm pro- posed by Afonso et al.
For example, a set of two peaks in the order: negative and positive, within the QRS complex would suggest that the QRS configuration is a QR com- plex.The classification accuracy was obtained by evaluating each class separately, i.e. if the manual annotated class was a positive T-wave and the algorithm classified it as aPeak -9.3 ± 28.9 61.3 %Offset -12.4 ± 41.2 49.4 % Table 2.
