问题 肺动脉闭锁合并室间隔缺损时
选项 A.全心扩大,左室为著 B.全心扩大,右房为著 C.左室壁增厚 D.肺动脉位于主动脉前方 E.不伴有动脉导管未闭
答案 B
解析 :室水平出现双向分流,右心室的血液不能进入肺动脉内,左右心室的血流均进入主动脉内,部分血流通过动脉导管进入肺动脉内,肺部的血流通过动脉导管及体肺侧枝供给。全心扩大,以右心房室为著,右室壁增厚。

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
