Original Abstract

Fractal dimensions of beat-to-beat series have been estimated by box-count algorithm in five New Zealand white rabbits and five isolated New Zealand rabbit hearts. In-vivo hearts beat-to-beat series have fractal dimension value equal to 1.49+/-0.03, whereas fractal dimension for ex-vivo hearts series is equal to 1.45+/-0.14. The fractal dimension of in-vivo hearts beat-to-beat series does not statistically differ (a = 0.05) from those of the isolated hearts, indicating that fractal features of heart rate variability are probably predominantly affected by intrinsic behaviour of the heart.
