초록
In this paper, we proposed complex demodulation method(CDM) to visualize the instantaneous frequency change of LF component and HF component of HRV signals, which represent the dynamics of sympathetic and parasympathetic (vagal) tone, respectively. As we know the range of the center frequencies of each autonomic tones, we could apply complex demodulation method. To simulate the heart rate variability signal, the IFPM model was adopted for generation of simulated cardiac event series. Then, we can visualize and access the dynamic changes of LF and HF component of autonomic tones in the time-frequency domain.
