Abstract
The words we use to describe a medical condition should match our knowledge of it. Unfortunately, at times, the words we used long ago persist after new knowledge of the subject has become apparent; so it is with left and right ventricular conduction system abnormalities. The words left or right bundle‐branch block no longer reflect our knowledge of the condition. Accordingly, this essay describes a new terminology that more accurately describes the numerous abnormalities that compose left and right ventricular conduction system block as well as their numerous subsets. A brief account of the cardiac conditions associated with the conduction defects is also presented.
Keywords: left ventricular conduction system abnormalities, right ventricular conduction abnormalities, new terminology for ventricular conduction system abnormalities
