抄録

We have reported the fuzzy-rates control by 2 parameters (minute ventilation, MV and oxygen saturation, OS) in rate adaptive cardiac pacing. Although the overall agreement between fuzzy-rates and target rates was satisfactory, the fuzzy-rates before and after exercise were almost at the same level (fuzzy-rates immediately decreased to the restinglevel before exercise, as far as MV and OS are used as the rate-controlling parameters, it is impossible to keep the fuzzy-rates higher after exercise because MV and OS are almost the same level before and after exercise. To improve this, we propose to add one more parameter which has generally the different values before and after exercise. We developed the automatic generation method of control rules for the 3 parameters pacing system and demonstrated its feasibility using MV, OS, and temperature, as the 3rd parameter. The preliminary simulation results were satisfactory. Automatic tuning methods of membershi functions and controlrules are under study.
