ECG Features
Figure 1: ECG Strip[1]
Aberration or aberrant conduction is conduction of the supraventricular impulse to the ventricles in a notably different manner from the usual conduction.[2] Aberration is seen as a bundle branch block pattern (wide QRS complex); aberration occurs as a right bundle branch block in 80% of the cases and can also be seen as a left bundle branch block in abnormal hearts.[2]
Clinical Significance
Classification of a wide QRS complex as aberrant conduction helps to rule out the diagnosis of premature ventricular contractions.[2]
