摘　　要：本文介绍了一种独立的QRS波检测模块。它应用自动增益控制并优化了二阶差分QRS波检测算法 ,使用简单 ,不需要任何控制输入 ,因此可以应用于多种场合。在 32名志愿者参加的与压力型指脉模块的对照实验中 ,每次 30秒脉搏 (QRS波 )计数差别合理地保持在一个以内 ,满足了设计要求。A QRS detection module was designed for calculating heart rate in the seated step test, which adopted auto gain control (AGC), optimized two order differential QRS complex detection algorithm. Without any control input, it is easy to use and can be applied in many cases. By testing with 32 volunteers, compared with pressure type pulse module, the differences of pulse counts(30 seconds each time) were kept less than one beat. The result was reasonable and indicated the design meets out requirements.
