Computer Analysis and Simulation of VCG Signals in the Frequency Domain

The analysis of full cycle VCG tracing and VCG segments in the frequency domain up to 80 Hz is reported. Data refer to adolescent normal subjects. The signals are also simulated with simple functions related to those used in the time domain and discussed in a previous paper. Each function depends on a given number of parameters, the average values of which and standard deviations are commented. Reconstructed signals are also discussed together with the frequency spectra and compared with the experimental spectra. The effects resulting from the time delays between P- and T-waves and the QRS-complex are also discussed.
