问题 关于正常人Q波的描述,错误的是
选项 A.Q波振幅<1/4R B.Q波时间<0.04s C.aVR导联可见深而宽的Q波 D.V导联可呈QS波 E.V~V导联可有小q波
答案 E
解析 :正常情况下V、V导联可呈QS型,但V~V导联r波前不应有q波(包括Q波和q波),若出现q波,无论再小也属异常。

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.
