Lyme disease is the most prevalent arthropod zoonosis in the Northern hemisphere
Lyme carditis (LC), first reported in 1980, occurs in 1.5–10% of untreated adults in USA
Symptoms develop on average within a month after the onset of erythema migrans
Symptoms range from asymptomatic to dyspnea, syncope, chest pain, and fluctuating degrees of atrioventricular block
Temporary pacing is usually necessary in approximately 30%
Prognosis is favorable and complete recovery occurs in more than 90%
Tx typically consists of three weeks of oral or parenteral antibiotics after continuous cardiac monitoring in any symptomatic patients
