WebNov 11, 2024 · A widened QRS complex (≥120 milliseconds) occurs when ventricular activation is abnormally slow for one of the following reasons (see 'Differential diagnosis of WCT' below): • The arrhythmia originates outside of the normal conduction system and below the AV node (ie, ventricular tachycardia [VT]) WebSep 28, 2024 · The term narrow QRS tachycardia indicates individuals with a QRS duration ≤120 ms, while wide QRS tachycardia refers to tachycardia with a QRS duration >120 ms. 1 Narrow QRS complexes are due to rapid activation of the ventricles via the His–Purkinje system, suggesting that the origin of the arrhythmia is above or within the His bundle.
WebIf QRS duration is ≥ 0,12 seconds (120 milliseconds) then the QRS complex is abnormally wide (broad). This is very common and a significant finding. The reason for wide QRS … WebNonspecific intraventricular conduction delay exists if the ECG displays a widened QRS appearance that is neither a left bundle branch block (LBBB) nor a right bundle branch block (RBBB). Thus, the appearance of nonspecific intraventricular conduction delay may be rather nuanced.
WebAug 30, 2008 · When the heart rate is fast and the QRS wide, the challenge for the cardiologist is to differentiate bundle branch block from other causes such as ventricular pre-excitation, the use of class IC drugs leading to rate-related QRS widening, and in particular ventricular tachycardia. WebApr 4, 2024 · A widened QRS (≥120 ms) occurs when ventricular activation is abnormally slow. The most common reason that a QRS is widened is because the arrhythmia originates below the His bundle in the bundle branches, Purkinje fibers, or ventricular myocardium (eg, ventricular tachycardia).
WebAmong the heart failure population, 20.8% of the subjects had a QRS duration ≥ 120 ms. A total of 425 men (24.7%) and 296 women (16.9%) had a prolonged QRS duration (p < 0.01). There was a linear relationship between increased QRS duration and decreased ejection fraction (p < 0.01). A prolonged QRS duration of 120 to 149 ms demonstrated ...
WebObjectives: Wide QRS duration and ventricular pacing are common in recipients of continuous-flow left ventricular assist devices (CF-LVADs) but their impact on outcomes remains unclear.
