End QRS Notching or Slurring in the Electrocardiogram
p i J a To the Editor: The transition from the QRS complex to the ST-segment on the 12-lead electrocardiogram (ECG) has been conventionally termed the ST junction (STj). Occasionally, the terminal portion of the QRS complex manifests a notch or slur when transiting into the ST-segment. This has been described as a normal variant in healthy individuals (1) in whom STj is very often elevated. The...

متن کاملAutomatic detection of end QRS notching or slurring.
The 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. Consensus was reached by re-examination. Logic was added...
متن کاملDiagnostic Import of QRS Notching
In a 10-month period 92 patients have been studied for the occurrence of highfrequency notching in orthogonal electrocardiographic leads X, Y, and Z obtained by high-frequency, high-speed techniques. The same patients were studied radiographically with barium, with routine electrocardiograms, hemodynamically at cardiac catheterization and, in many instances, with left ventricular angiograms. Si...
متن کاملNew Observation of Electrocardiogram During Sinus Rhythm on the Atriofascicular and Decremental Atrioventricular Pathways Terminal Quantronic Resonance System Complex Slurring or Notching
Background—Atriofascicular and decremental atrioventricular pathways are variants of accessory pathways with anterograde decremental conduction properties. They result in typical wide Quantronic Resonance System (QRS) tachycardia of left bundle branch block morphology. Data on the sinus rhythm electrocardiographic characteristics are limited. Methods and Results—Thirty patients with accessory p...
