Recurrence quantitative analysis of heart rate variability during intradialytic hypotension

Recurrence quantitative analysis (RQA) of heart rate variability (HRV) is helpful for the non-invasive study of the regulation of the cardiovascular system by the autonomic nervous system. HRV monitoring during hemodialysis (HD) sessions of end-stage renal disease patients reflects a sympathetic hyp...

Description
Summary:Recurrence quantitative analysis (RQA) of heart rate variability (HRV) is helpful for the non-invasive study of the regulation of the cardiovascular system by the autonomic nervous system. HRV monitoring during hemodialysis (HD) sessions of end-stage renal disease patients reflects a sympathetic hyperactivity that has been proposed as an early marker of intradialytic hypotension (IDH). However, neither intradialytic HRV analysis nor episodes of IDH have been explored from the RQA perspective. We studied the HRV dynamics with linear and RQA indices during intradialytic recordings ( N  = 38) in which 39.5% of patients presented IDH. Patients with IDH showed a restricted HRV during the whole HD compared to patients with stable blood pressure ( p
