Dr Sasse is certainly justified in protesting the use of the term "partial trifascicular block" for the triad of a right bundle-branch block, anterior divisional block, and firstdegree AV block. My statement that such a combination "could" be called a partial trifascicular block was not meant to imply that it always was such but that if you thought that the AV block was due to a block in the remaining fascicle, then (and only then) should it be called a partial trifascicular block. I trust that the ambiguity of my statement does not detract from the point that such a combination of blocks should not be called "bilateral bundle-branch block."
