As a time-domain-based description of cardioelectrical signals,ECG may also be represented with frequency domain through Fourier transformation. The frequency-domain-based analysis is more precise, especially possible for a definite introduction of phased messages. The ECG of I, V5 and aVR leads were recorded on a magnetic tape (FM) by passing signals respectively through HP, LP and BP filters with different cut-off frequencies and by means of diagraming of filtered signals, a comparative analysis could be carried out for time and frequency-domain parameters. Results showed that, (1) in the power spectrum of cardioelectrical signals, the first 5 spectrum peaks counted from LF side accounted for 50-60% 癴 the total power spectrum energy, and the first spectrum peak was the highest, its amplitude accounting for one third of total energy; (2) P-wave correlated mainly with spectrum peaks 1-13> (3) a frequency lower than g Hz had an influence upon the QRS shape and frequencies higher than 8 Hz had an influence on the amplitude of R-wave; (4) the T-wave structure correlated mainly with the spectrum peak 4, and frequencies of 3-13 Hz had an influence on the amplitude of T-wave.
