Abstract:
A 23-year old patient suffered from transient oligoarthritis and second degree AV block. The diagnosis of stage II systemic Lyme borreliosis was supported by a history of tick bites and the detection of both IgG and IgM borrelia antibodies in the patient's serum. The ECG-findings (bradyarrhythmia and AV block II) were detected several weeks after the onset of arthritis, whilst the patient reported no cardiac symptoms. Treatment was started with ceftriaxone and then continued with doxycycline because of an allergic reaction to the first antibiotic.
