WebSince aberrancy is almost always in the form of a bundle branch block morphology, V1 is the best lead for differentiating RBBB from LBBB; RBBB creates a positive deflection, and LBBB, a negative deflection. Therefore, the first order of business is to identify the direction of QRS forces in V1. WebAshman phenomenon, also known as Ashman beats, describes a particular type of wide QRS complex, often seen isolated that is typically seen in atrial fibrillation.

"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.
