Power spectral analysis of the heart rate was compared with standard tests of autonomic function performed on 15 insulin-dependent diabetic patients with symptoms of autonomic dysfunction. The high-frequency power, low-frequency power, and total power of the heart rate power spectrum measured in the supine position--possible measures of parasympathetic(More)
In May, 2007, a 47-year-old man was admitted with a 1-week history of productive cough, pleuritic chest pain, increasing shortness of breath, fever, and myalgia. He smoked ten cigarettes per day, and worked as a welder; he had no other medical history of note, and had previously been in good health. On presentation, his respiration rate was 30 breaths per(More)
Heart rate variability (HRV) is an important tool to analyze the autonomic function. It therefore has a special interest for early detection and ensuing treatment of autonomic neuropathy in diabetic patients. The aim of this work is to present a brief historical review of HRV, as well as a technical review of the most common methods to measure it. In this(More)
We compared autonomic function in 26 patients infected by the human immunodeficiency virus (HIV) (18 AIDS and 8 ARC) to 22 controls. A significant decline in autonomic function was present across groups. Autonomic dysfunction correlated strongly with signs of HIV-associated nervous system disease. We observed significant differences across groups in tests(More)
The aim of this report was to study the cardiovascular autonomic tests in the evaluation of diabetic patients with gastroparesis. Forty diabetic subjects were divided into two groups: one group with gastroparesis (GP, n = 20) and another group paired by age and duration of diabetes without any complaint of autonomic neuropathy (DC, n = 20). They were(More)
