[Complete atrio-ventricular block as a first symptom of borreliosis: antibiotic treatment instead of pacemaker implantation].

We present a 46-year-old male patient with complete atrio-ventricular block. A inflammatory etiology was suspected and finally lyme carditis was diagnosed. The conduction abnormalities disappeared with antibiotic treatment and a pacemaker implantation was not needed. Further follow-up of two years was uneventful.
