论文摘要
快速傅立叶变换（FFT）依赖于HRV频域分析技术。它需要重新采样固有的不均匀采样的心跳时间序列（RR转速图），以产生心跳的均匀抽样时间序列。然而，在估计人工RR转速图时，发现心跳时间的重新采样 - 发现序列会产生重大误差。
Fast Fourier Transform (FFT) relies on the HRV frequency-domain analysis techniques. It requires re-sampling of the inherently unevenly sampled heartbeat time-series (RR tachogram) to produce an evenly sampled time series of the heartbeat. However, re-sampling of the heartbeat time -- series is found to produce a substantial error when estimating an artificial RR tachogram.
