Excerpt

Lyme disease is the most common of tick-borne illnesses in the United States. It is a multisystem disease caused by infection with Borrelia burgdorferi. One of the complications is carditis, which reportedly ranges between 1% and 10 % of the total Lyme disease cases, occurring within weeks to months of the onset of infection. It presents in the early disseminated stage, the second phase of the disease. The most prominent manifestations are conduction system disturbances involving the atrioventricular (AV) node. This leads to several degrees of heart block that, in some cases, require the placement of a temporary pacemaker.

Other forms of presentation include myocarditis, endocarditis, valvular heart disease, pericarditis, and myopericarditis. However, such conditions have been reported less frequently than the typical conduction system abnormalities.
