Untreated Lyme disease can affect the heart in up to 10% of patients. Its clinical outcome and severity vary, ranging from asymptomatic minor conduction disturbances to potentially fatal arrhythmias and severe heart failure. A history of a tick bite or a typical previous skin lesion (Erythema migrans) may be absent; clinicians should therefore keep a low threshold of suspicion when facing cardiac manifestations in a patient potentially exposed to the disease in endemic areas. We report the case of a patient with Lyme carditis expressed by variable degrees of atrio-ventricular block and review the literature.
未经治疗的莱姆病在高达10%的患者中会影响心脏。其临床结果和严重程度各不相同，从无症状的轻微传导障碍到潜在致命的心律失常和严重心力衰竭。可能没有蜱虫叮咬史或先前典型的皮肤病变（游走性红斑）；因此，临床医生在面对流行地区可能接触过该疾病的患者出现心脏表现时，应保持较低的怀疑阈值。我们报告一例以不同程度房室传导阻滞为表现的莱姆心肌炎患者，并对文献进行综述。
