Chaotic Global Metric Analysis of Heart Rate Variability Following Six Power Spectral Manipulations in Malnourished Children

Background and Aim: The study objective was to assess chaotic global metrics in malnourished children following power spectral manipulations. Methods: We evaluated the complexity of heart rate (HR) variability (HRV) subjects via six spectra (Welch, multi-taper method (MTM), Burg, covariance, Yule-Walker, periodogram) then, when adjusted by MTM parameters, for further refinement. Seventy were split equally (controls & malnourished) HR monitored 20 min; 1000 RR-intervals attained HRV analysis. Results: results stipulate that CFP1 (chaotic forward parameter) CFP3 are best distinguish two groups. most appropriate Welch, MTM, Yule-Walker. Results indicate calculated using is combination discriminate between Yet, if RR intervals set 400, discrete prolate spheroidal sequences (DPSS) 3, Thomson’s nonlinear ‘adaptive’, a greater level significance can be achieved (Cohen’s ds = -1.57). This significantly outperforms under default conditions (Glass’s ∆ Delta -1.06, Cohen’s -0.95). Conclusion: Malnourished have lower response than control group. with aforementioned settings these groups on basis intervals. It has greatest ds. Our data suggest impaired autonomic function children, which may consequences cardiovascular risks.
