Despite multiple ECG algorithms and rules to distinguish VT from SVT with aberrancy (Brugada, Wellens, Vereckei, R wave peak time) none are better than 90% specific to identify SVT with aberrancy. Web9 aug. 2024 · Aberrancy refers to a rhythm with abnormal conduction. Most often it refers to a patient with a bundle branch block (BBB). If a patient has a BBB at baseline and they develop tachycardia, then this BBB will persist, and it will present as a wide complex tachycardia. SVT with Aberrancy is one example of this.
