The cardiac features of Lyme disease usually occur within weeks to months of the infecting tick bite; the result may be disruption of the conduction system, leading to heart block and muscle dysfunction, causing a mild myopericarditis. Lyme carditis is usually mild, although permanent heart block and a few fatalities claimed to be due to Lyme carditis have been reported, the latter usually with poor documentation. In general, Lyme carditis is treatable and curable with antibiotic regimens in current use. Recent reports have suggested that Lyme disease may be a cause of chronic congestive cardiomyopathy. Lyme carditis should be considered in the proper clinical setting with appropriate use of diagnostic tests, recalling that patients with carditis early in Lyme disease may be seronegative and that all patients who are seropositive do not necessarily have Lyme disease.
莱姆病的心脏症状通常在被感染蜱虫叮咬后的数周或数月内出现；其结果可能是传导系统紊乱，导致心脏传导阻滞和肌肉功能障碍，引发轻度心肌心包炎。莱姆病性心脏炎通常症状较轻，尽管有报道称出现了永久性心脏传导阻滞以及一些据称由莱姆病性心脏炎导致的死亡病例，但后者的记录往往不佳。总体而言，目前使用的抗生素治疗方案可治疗并治愈莱姆病性心脏炎。最近的报告表明，莱姆病可能是慢性充血性心肌病的一个病因。在适当的临床环境中，应合理使用诊断测试来考虑莱姆病性心脏炎，要记住莱姆病早期患有心脏炎的患者可能血清学检测呈阴性，而且所有血清学检测呈阳性的患者不一定都患有莱姆病。
