Original Abstract

Heart rate variability (HRV) in in-vivo and isolated hearts was evaluated by complex correlation measure (CCM) and Poincaré descriptors SD1 and SD2. CCM quantifies temporal aspect of Poincaré plot; SD1 and SD2 quantify final shape of Poincaré diagram only. Five in-vivo and five isolated New Zealand rabbit hearts were used in the study. When used for distinguishing between in-vivo and ex-vivo condition of the heart, CCM has been proved as a more sensitive quantifier of Poincaré plot as compared to SD1 and SD2. Decrement of CCM, caused by heart excision, was statistically significant in contrast to decrements of SD1 and SD2, respectively.
