问题 男性,30岁,体检心电图示窦性心律,正常心电图。 该男性P波的方向应为
选项 A.Ⅱ、aVL、V导联负正双向,aVR导联正负双向 B.Ⅰ、Ⅱ、Ⅲ、V~V导联直立,aVR导联倒置 C.Ⅰ、aVL、V、V导联倒置,aVR导联直立 D.Ⅱ、Ⅱ、aVF、V导联倒置,aVR导联直立 E.Ⅰ、Ⅱ、aVF、V、V导联直立,aVR导联倒置
答案 E
解析 :正常窦性P波电轴在0°~+75°之间,大多数在+45°~+60°gif">、V导联直立,aVR导联倒置Ⅲ导联P波可直立、双向或倒置

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.
