Energy Spectrum ECG frequency and harmonic frequency components of energy density distribution and the relationship between age
Entropy of heart rate [7],[link widoczny dla zalogowanych], the other is the energy spectrum,[link widoczny dla zalogowanych], energy spectrum analysis of heart rate is below the fundamental frequency of the frequency components (<0.5Hz) in the energy distribution of [1], two methods different age groups reveals the complexity of heart rate fluctuations are different. This study is the energy spectrum analysis method, but analysis of the frequency range is greater than 0.5Hz and calculated parameters are completely different. As we all know, of the lower frequency required the longer the signal recorded, Sakata, etc. In order to study the lower frequencies up to 6.1 × 10 a Hz, recorded the 24h ECG data L2], therefore, presented here research method has the advantages of relatively easy to achieve. Concluded that: distribution index presented here and the harmonic frequency and fundamental frequency ratio of energy density as measured by heart rate fluctuation can be a measure of the complexity of the indicators, and has simple calculation, the advantage of easily.
