Four cases showing unusual patterns of conduction produced by pacemaker stimuli are presented. Some of the possible explanations for these phenomena are considered. It is suggested that the pacemaker stimuli in these cases were conducted through specialized conductive tissue rather than preferentially through the myocardial fibers. Thus, the pattern of right bundle branch block occasionally produced by transvenous catheter pacemakers in the right ventricle does not necessarily imply that the catheter has perforated the septum.
