Improve the identification of the R-peak using cubic spline interpolation
1 | qrs_interpolate(ind.r, sig, window.length = 6, n.spline = 1000)
|
ind.r |
A vector with the indices of the R-peaks |
sig |
A vector containing the ECG signal |
window.length |
The length of the window in samples. Default is 6. |
n.spline |
The number of splines to use. |
A matrix with two columns. The x-index of the R-peaks are in the first column and the y-values of the ECG signal are in the second column
