Evaluation of Dimension of Integral Correlation for ECG
To investigate complexity of ECG data, was used dimension of integral correlation by Kolmogorov. Data array was formatted from twelve synchronically registered ECG leads. Length of registration – 10sec, discretization rate 500Hz. Correlation dimension was computed for different leads , with different loads, for both sex and with given extrasystoles. As results showed, there are some essential differences between complexity of leads for both sex, when some physical loads were being performed. The correlation dimension for studied leads with extrasystole was higher for all leads. Ill. 8, bibl. 5 (in Lithuanian; summaries in Lithuanian, English and Russian).
