Lyme carditis (LC) is an early-disseminated manifestation of Lyme disease, most commonly presenting as a high-degree atrioventricular block (AVB). The degree of AVB can fluctuate rapidly within minutes, and progression to third-degree AVB is potentially fatal if not recognized and managed promptly. However, the AVB in LC is often transient and usually resolves with appropriate antibiotic therapy. LC should be on the differential diagnosis in young patients presenting with new high-degree AVB and factors that increase the index of suspicion for Lyme disease. The Suspicious Index in Lyme Carditis (SILC) score helps clinicians risk-stratify for LC. A systematic approach to the diagnosis and treatment of LC minimizes the unnecessary implantation of permanent pacemakers.
莱姆心炎（LC）是莱姆病的早期播散表现，最常见的表现为高度房室传导阻滞（AVB）。AVB 的程度可在数分钟内迅速波动，如果不能及时识别和处理，进展为三度 AVB 可能是致命的。然而，LC 中的 AVB 通常是短暂的，通常随着适当的抗生素治疗而消退。LC 应作为年轻患者新发高度 AVB 的鉴别诊断，并且应增加对莱姆病的怀疑因素。莱姆心炎可疑指数（SILC）评分有助于临床医生对 LC 进行风险分层。对 LC 的诊断和治疗采用系统方法可以最大限度地减少不必要的永久性起搏器植入。
