  * 病历业务实现
  * 
  * 修复 Bug #562：
- *   原实现未限制查询范围且未使用分页，导致全表扫描或关联查询过多历史数据，
- *   响应时间远超 2 秒。同时前端未正确处理异常状态导致 loading 卡死。
- * 
- *   解决方案：
- *   1. 使用 PageHelper 限制单次查询数量（默认 50 条），满足首屏快速加载需求。
- *   2. 添加 @Transactional(readOnly = true) 优化只读事务性能。
- *   3. 精确过滤 doctor_id 与 status='PENDING'，避免无效数据拉取。
+ *   根因：原实现未使用分页插件，且采用循环查询患者基本信息（N+1问题），导致全表扫描与多次DB交互，
+ *         数据量稍大时响应时间远超2秒。
+ *   修复方案：
+ *   1. 引入 PageHelper 进行物理分页，限制单次查询数据量。
+ *   2. 优化 Mapper SQL，使用 LEFT JOIN 一次性关联患者表，消除 N+1 查询。
+ *   3. 仅查询必要字段（避免 SELECT *），减少网络传输与内存开销。
+ *   4. 增加性能日志埋点，便于后续监控。
