Excerpt:
The tick bite transmitted Lyme disease is one of the most common
antropozoonosis, about 10 000 new infections are reported in
Hungary each year.
The progress and clinical presentation can vary, and carditis can
occur in later stages. A serologically verified Lyme disease
caused third degree atrioventricular block in young male
presenting with presyncope. Based on the tick-bites mentioned a
few weeks prior to hospital admission, Lyme carditis was
considered with the administration of antibiotics and monitor
observation.
Typical skin lesions were not recognized and laboratory findings
showed no pathology. An electrophysiological study recorded a
predominant supra-His atrioventricular block. Total regression of
conduction could be detected later and the serological tests
established an underlying Lyme disease. Currently no definite
treatment recommendation is available for the potentially
reversible Lyme carditis. The tick bite seemed to be the key on
our way to diagnosis; however, serological tests proved the
disease to be older than one year. A detailed medical history and
serological tests are essential in identifying the cause and
pacemaker implantation can be avoided. Orv. Hetil., 2010, 39,
