Development of causal interactions between systolic blood pressure and inter-beat intervals in adolescents

Original language description

Systolic blood pressure (SBP) changes control the cardiac inter-beat intervals (IBI) duration via baroreflex. Conversely, SBP is influenced by IBI via non-baroreflex mechanisms. Both causal pathways (feedback ? baroreflex and feedforward ? non-baroreflex) form a closed loop of the SBP ? IBI interaction. The aim of this study was to assess the age-related changes in the IBI ? SBP interaction. We have non-invasively recorded resting beat-to-beat SBP and IBI in 335 healthy subjects of different age, ranging from 11 to 23 years. Using a linear autoregressive bivariate model we obtained gain (GainSBP,IBI, used traditionally as baroreflex sensitivity) and coherence (CohSBP,IBI) of the SBP?IBI interaction and causal gain and coherence in baroreflex (GainSBP IBI, CohSBP IBI) and coherence in non-baroreflex (CohIBI SBP) directions separately. A non-linear approach was used for causal coupling indices evaluation (CSBP IBI, CIBI SBP) quantifying the amount of information transferred between signa
