A method of multilead ECG character points detection is introduced in this study. The method includes two main sections: the detection of single lead character points and determination of global character points. The method of single lead character points detection is similar to the traditional ones that use the first differential signal of ECG. While some special modification is adopted. The multilead...
The analysis of heart rate variability (HRV) has become a tool for noninvasively detecting the cardiovascular modulation of autonomic nervous system (ANS). Traditional analysis in frequency-domain mainly includes calculating the power and the peak frequency of each physiological frequency component. Whether employing the non-parametric or parametric method to estimate the power spectrum density (PSD),...
