Abstract:
Lyme disease is the most common tick-borne disease in Europe and in the United States. In comparison to dermatological, neurological and rheumatological manifestations, heart disease is quite rare. Atrioventricular heart block is nevertheless the most frequent cardiological manifestation. We hereby report the case of a patient with high degree heart block due to Lyme disease. We focus on the electrocardiographical evolution during antibiotic therapy, as well as on microbiological and diagnostic aspects. Lyme disease is a rare cause of conduction disturbances but it is treatable and potentially reversible.
