Atrio-ventricular block

Excerpt:
A 36year old male patient presented to emergency cardiology
department because of fatigability. ECG revealed high grade II
atrio-ventricular block and bradycardia of 31beats/min. An
erythema increasing in size to up to 7-8cm in diameter appeared a
month earlier and spontaneously resolved within 10days.
ELISA testing for antibodies against Borrelia burgdorferi IgM was
positive and IgG titer was 1:40. Intravenous ceftriaxone 2g qod,
and 0.5g metronidazole tid lead to regression of grade II block
to grade I block within 2days. Grade I block persisted for an
additional 10days. This is a relatively rare case of early
occurrence of Lyme carditis within one month of exposure as the
first sign of Lyme disease dissemination. Copyright (c) 2010.
