Lyme disease is the most common of tick-borne illnesses in the United States. One of the complications is carditis, which reportedly ranges between 1 and 10 % of the total Lyme disease cases.[1][2] 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 affection 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.[1][3][4][5]
