【Abstract】 HRV analysis system based on Matlab is developed. The system has relatively completed functions, which include R wave detecting and locating, HRV time domain analysis, periodic map and AR modeling frequency domain analysis and Lorenz scattered plot. Multiple functions are used in frequency domain analysis. We apply the system to diabetes. It reveals that the system has certain research and clinic practicality.更多还原
