不少扩张型心肌病(DCM)患者体内可检出心脏自身抗体,但这些抗体是否参与发病机理尚属未知。本文研究伴遗传性心脏传导系统及心肌疾病的一个Ohio家族中的41个成员。以配基结合抑制试验(LBIA)、β_1-受体多肽酶联 Many patients with dilated cardiomyopathy (DCM) can detect cardiac autoantibodies in vivo, but whether these antibodies are involved in the pathogenesis is unknown. This article investigates 41 members of an Ohio family with hereditary cardiac conduction system and cardiac disease. Ligand binding inhibition test (LBIA), β 1 -receptor polypeptide coupling
