2. Aberrant A-V impulse propagation in the dog heart: a study of functional bundle branch block;Moe, G.K.; Mendez, C.; Han, J.;Circ Res,1965
3. Rate dependent aberrancy;Fisch, C.; Zipes, D.P.; McHenry, P.L.;Circulation,1973
4. Sino-auricular block, interference dissociabundle-branch must be affected in order to slow contion, and different recovery rates of excitation in the duction, the thickness of the left bundle-branch bundle branches. Br HeartJ' 1949; 11: 230-6. argues against this hypothesis. This objection does not seem particularly valid in the presence of an abnormal bundle because of the likelihood of a reduced number of conducting fibres. Other investigators point;Burchell, H.B.
