Autonomic functions in acrocyanosis assessed by heart rate variability.
OBJECTIVE To evaluate the autonomic activity of patients with acrocyanosis by using heart rate variability indices. MATERIAL AND METHODS The study group consisted of 24 patients with acrocyanosis and the control group contained 22 sex- and age-matched healthy subjects. All subjects underwent 24-hour Holter monitoring. Among the heart rate variability (HRV) parameters, time-domain and frequenc...
متن کاملAutonomic Dysfunction and Risk Stratification Assessed from Heart Rate Pattern
The modulation of the autonomic nervous system (ANS) under physiological and pathophysiological conditions is in focus of recent research. Many patients with cardio- and cerebrovascular diseases display features of sympathovagal dysregulation. Measuring specific ANS parameters could improve risk stratification. Thus, the early diagnosis of ANS dysfunction in these patients poses a great challen...
متن کاملAutonomic nervous function during haemodialysis assessed by spectral analysis of heart-rate variability.
1. Short-term autonomic response to haemodialysis-induced hypovolaemia was studied in 30 patients undergoing chronic haemodialysis by analysing power spectra of heart-period variability. Patients were classified as haemodynamically stable (15 patients) and unstable (15 patients) according to their past history of cardiovascular collapse during the treatment. Blood volume, systolic arterial pres...
متن کاملHeart Rate Variability for Quantification of Autonomic Dysfunction in Fibromyalgia.
OBJECTIVE To quantify autonomic dysfunction in fibromyalgia patients compared to healthy controls using heart rate variability (HRV). METHODS Sixteen patients with fibromyalgia and 16 healthy controls were recruited in this case control study. HRV was measured using the time-domain method incorporating the following parameters: total heartbeats, the mean of intervals between consecutive heart...
متن کاملNonstationary time series analysis of heart rate variability
An analysis of the RR-interval time series, t i , is presented for the case in which the average time, ¯ t, changes slowly. In particular, ¯ t and a short-time scale variability parameter, V , are simultaneously measured while ¯ t decreases for subjects in the reclined position. The initial decrease in ¯ t is usually linear with V yielding parameters that can be related to physiological quantit...
