QRS Detector for Seated Step Test

PAN Dongli, ZHANG Yonghong, BAI Jing. Department of Biomedical Engineering, Tsinghua University, Beijing 100084  
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.
