We report upon a case of total retraction of an electrode (Twiddler syndrom) in 
an infected pacemaker battery. The silk-thread fixation was still fastened at 
the right place on the electrode; the tissue owing to the inflammation was no 
longer sufficient as a fixation point. The casues of this total retraction of 
the electrode are the following factors: the battery hat sufficient freedom of 
movement for rotation following exudation into the pacemaker cavity, the 
electrode was elastic and above all the pacemaker system was infected which 
could no longer guarantee a sufficient fixation of the electrode in the infected 
tissue. Attention is drawn to the necessity to remove an infected pacemaker 
system.
