心电图分析中HRV的各种计算方法，适用于心电图研究。(various calculation methods of HRV for Electrocardiogram (ecg)analysis which are applicable in the study of ecg.)

Thi is a Binary BAT algorithm

unit should be promoted in future work. The real implementation of the system is an issue that has been mentioned and should be analyzed while the simulation procedure exalts. Other simulation programs such as PSpice should be used to compare their results. The inverters need to develop in order to be more efficient and up to date, to
