问题听诊心率正常且节律整齐，可排除哪些心律失常

选项 A．室性期前收缩三联律 B．一度房室阻滞 C．二度Ⅰ型房室阻滞 D．心房扑动 E．三度房室阻滞

答案 ACE

解析：室性期前收缩比窦性激动提前、二度Ⅰ型房室阻滞QRS波群有脱落，听诊心律均不齐，三度房室阻滞听诊节律整齐，但心室率缓慢不正常。

错误啦！

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.
