OBJECTIVE: The aim of this study was to evaluate cardiac autonomic nervous system function using Holter-derived and standard electrocardiographic parameters in patients with myotonic dystrophy (dystrophia myotonica, DM) and no clinically overt heart involvement. METHODS: Eighty-four DM patients without conditions potentially influencing cardiac autonomic function were enrolled in the study: 44 with DM type 1 and 40 with DM type 2 (mean age 34.9 ± 11.5 and 47...

PURPOSE: Adults after surgical repair of tetralogy of Fallot (ToF) may have impaired vascular and cardiac autonomic function. Thus, we wanted to assess interrelations between heart rate variability (HRV) and heart rate recovery (HRR), as parameters of cardiac autonomic function, and arterial stiffness, as a parameter of vascular function, in adults with repaired ToF as compared to healthy controls. METHODS: In a case-control study of adults with repaired ToF and healthy age-matched controls we measured: 5-min HRV variability (with time and frequency domain data collected), carotid artery stiffness (through pulse-wave analysis using echo-tracking ultrasound) and post-exercise HRR (cycle ergometer exercise testing)...

PURPOSE: The contribution of diastolic blood pressure measurement to the diagnosis of classical orthostatic hypotension is not known. We aimed to explore the prevalence of isolated systolic and diastolic orthostatic hypotension components in patients with syncope and orthostatic intolerance. METHODS: A total of 1520 patients aged >15 years with suspected syncope and/or symptoms of orthostatic intolerance were investigated in a tertiary center using tilt-table testing and continuous non-invasive blood pressure monitoring...

PURPOSE: The ability of a blood vessel to change diameter in response to a change in carbon dioxide concentration is often referred to as vasomotor reactivity. This study aimed to determine whether vasomotor reactivity is impaired in patients with idiopathic Parkinson's Disease in comparison to healthy controls. METHODS: Transcranial Doppler was used to measure cerebral blood flow velocity in the middle cerebral arteries at baseline and under hypocapnic conditions in 40 patients with idiopathic Parkinson's disease and 50 healthy controls...

PURPOSE: The blood pressure "error signal" represents the difference between an individual's mean diastolic blood pressure and the diastolic blood pressure at which 50% of cardiac cycles are associated with a muscle sympathetic nerve activity burst (the "T50"). In this study we evaluated whether T50 and the error signal related to the extent of change in blood pressure during autonomic blockade in young and older women, to study potential differences in sympathetic neural mechanisms regulating blood pressure before and after menopause...

PURPOSE: To compare the order of presentation of bladder and motor symptoms between multiple system atrophy phenotypes. METHODS: Medical records were retrospectively reviewed in 144 patients. RESULTS: Bladder symptoms occurred either before or within 12 months after onset of motor symptoms in significantly more patients with the cerebellar phenotype than the parkinsonian phenotype (80 vs. 53%, p = 0.003); similar results were observed for urinary incontinence (79 vs...

Pure autonomic failure is a rare form of chronic autonomic failure manifesting with neurogenic orthostatic hypotension and evidence of sympathetic noradrenergic denervation unaccompanied by signs of central neurodegeneration. It has been proposed that pure autonomic failure is a Lewy body disease characterized by intra-neuronal deposition of the protein alpha-synuclein in Lewy bodies and neurites. A middle-aged man with previously diagnosed pure autonomic failure experienced a sudden, fatal cardiac arrest. He was autopsied, and tissues were harvested for neurochemical and immunofluorescence studies...

OBJECTIVE: To establish the validity of bedside sudomotor tests in a controlled prospective study. METHODS: Five different tests were used to assess presence of sweating at seven bilaterally symmetrical body loci, namely, examination with the unaided eye, visualization with light reflection, magnification with an ophthalmoscope, palpation of skin for slickness, and gliding the back of a spoon over the skin to detect friction. Sensitivity and specificity of these bedside tests were compared with the thermoregulatory sweat test in 130 subjects with generalized body sweating and 16 patients with complete anhidrosis...

PURPOSE: Postural tachycardia syndrome (POTS) is a disorder featured by orthostatic intolerance. The purpose of this study was to investigate the severity of quality of life issues in POTS patients. METHODS: Online surveys for health related quality of life, sleep quality, fatigue, pain, and suicidal ideation were completed by 624 POTS patients and 139 controls. RESULTS: People with POTS have significantly more days of poor physical health (p < 0...

PURPOSE: This study aimed at examining the autonomic cardiovascular modulation in well-trained masters and young cyclists following high-intensity interval training (HIT). METHODS: Nine masters (age 55.6 ± 5.0 years) and eight young cyclists (age 25.9 ± 3.0 years) completed a HIT protocol of 6 x 30 sec at 175% of peak power output, with 4.5-min' rest between efforts. Immediately following HIT, heart rate and R-R intervals were monitored for 30-min during passive supine recovery...
