Spontaneous progressive changes in systolic blood pressure (SBP) are not invariably followed by baroreflex-driven changes in pulse interval (PI). In order to quantify this phenomenon we propose a new index, termed Baroreflex Effectiveness Index (BEI), defined as the ratio between the number of times that SBP progressive changes are followed by progressive changes in PI in the same direction and the total number of SBP changes occurring in a given time window. In this study we applied this new index on data collected in two pilot groups of young and elderly subjects during spontaneous behaviour.
