[A symmetry approach to electrocardiogram analysis].
A qualitative characteristics of a symmetry of correlations in ECG parameters has been studied in experiments on rats with the adaptation syndrome and hypertonic patients (I-II stages). A geometrical model of cardiac cycle shaped as a rectangular triangle with temporal and amplitude ECG parameters as catheti. A total correlation between the ECG parameters is given: QT--QRS/QT--PQ.RR--PQ/RR--QRS = R--P/R--T = 1,309. In healthy individuals, the deviation from the ideal proportion constitutes less than 5%, and in patients with cardiovascular diseases, the deviations are substantial.
