问题 完全性房室传导阻滞与干扰性房室分离的主要区别是
选项 A.房室分离 B.P波与QRS波群无关 C.室性逸搏心律 D.PP间距小于RR间距 E.心室夺获
答案 D
解析 :完全性房室传导阻滞时,心房率>心室率,即PP间距小于RR间距;干扰性房室分离时,心室率可快于心房率,或者两者频率相近。

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.
