摘要

持续性心房麻痹的病人完全心脏传导阻滞和轻度二尖瓣功能不全提出。在植入永久性心脏脉冲发生器期间获得的左心房标本显示肥大和纤维化的证据;亚细胞退行性改变范围从接近正常到不可逆，因此提示心房麻痹可能是由于正常心房肌被无功能纤维组织取代。

Persistent atrial paralysis: Case report with light microscopy and ultrastructural analyses.

Persistent atrial paralysis in a patient with complete heart block and mild mitral insufficiency is presented. Left atrial specimens obtained during implantation of a permanent cardiac pulse generator showed evidence of hypertrophy and fibrosis; subcellular degenerative changes ranged from near normal to irreversible, thus suggesting that atrial paralysis may be due to the replacement of normal atrial muscle with nonfunctional fibrous tissue.
