Table 1.
The ratios of the total error pk ± SD for the HRV parameters with increasing magnitude of observational error σ. The pk values in the table are normalised and presented in %, following Eq. (2). The results are obtained from the MC simulations repeated 103 times for each signal of the MIT BIH Database separately.
