Triphasic qrs
WebJan 1, 1978 · Triphasic right bundle branch block-shaped QRS complexes in lead Vi are found in both supraventricular and ventricular tachycardia with, as stressed by Marriott and Sandier [3,6], a "classic" triphasic pattern highly suggestive for a supraventricular origin of the arrhythmia, especially when combined with initial negativity in leads I and Ve ... WebJan 1, 2024 · In contrast, supraventricular aberrancy beats tended to demonstrate triphasic (e.g., rSR’) QRS morphologies. They also noted the value of analyzing the initial vector of QRS activation for distinguishing PVCs and supraventricular aberrancy. They observed that if the initial vector of the wide complex beat was identical to that of the dominant ...
