Webb1 dec. 2024 · The ECG shows ventricular pacing in complexes 1, 4, 5, 8, 9, and 10, which exhibit the same QRS morphology ( Fig. 2 ). However, complexes 3 and 7 have a different morphology. Complexes 2 and 6 result from ventricular pacing after a premature atrial complex (PAC). The R-R intervals after beats 2 and 6 are much longer than those in the … Webb14 apr. 2024 · PR interval is short. There is slurring of the initial part of QRS—the delta wave (marked ⇩).

Webb30 maj 2024 · The representative QRS was created (in the same way as in QRS morphology determination) in each lead in which QRS notching and slurring was analyzed (V1, V2, V5, V6, I and aVL). The analyzed section of signal was shortened only to a part where mid-QRS notching and slurring can occur—the section between 40 ms after the QRS onset and … WebbThe purpose of this study was to define criteria suited to automated detection of end QRS notching and slurring and to evaluate their accuracy. One hundred resting 12 lead ECGs from young adult men, split randomly into equal training and test sets, were examined independently by two reviewers for the presence of such notching or slurring.
