Lyme disease, a tickborne infection caused by Borrelia burgdorferi, can affect cardiac tissue causing Lyme carditis. Patients with Lyme carditis most commonly present with varying degrees of atrioventricular block and rarely with sick sinus syndrome. A previously healthy 22 year-old male presented with syncope. His 2 week Holter monitor showed sinus pauses of 6.5 and 6.8 s. Lyme serology, including Western blot, was positive. A stress test, completed after 8 days of intravenous antibiotics for Lyme carditis, revealed no conduction abnormalities. He was discharged on 3 weeks of oral antibiotics and had no conduction abnormalities on subsequent follow-up.
莱姆病是一种由伯氏疏螺旋体引起的蜱传播感染，可影响心脏组织导致莱姆心肌炎。莱姆心肌炎患者最常见的表现是不同程度的房室传导阻滞，很少出现病态窦房结综合征。一名此前健康的22岁男性出现晕厥。他的2周动态心电图监测显示窦性停搏分别为6.5秒和6.8秒。包括免疫印迹法在内的莱姆血清学检查呈阳性。在针对莱姆心肌炎静脉注射抗生素8天后进行的应激试验显示没有传导异常。他接受了3周的口服抗生素治疗后出院，后续随访未发现传导异常。
