Portable Instrument for Autonomic Nervous System Analysis
نویسندگان
چکیده
The paper presents the implementation of a low cost, small size portable measuring system based on a personal digital assistant (PDA) for heart rate and blood pressure variability evaluation. The signals obtained from electrocardiogram (ECG) electrodes and non-invasive arterial blood pressure (BP) sensors are pre-processed using a set of filters for noise reduction and acquired using two analogue channels of a data acquisition board. A distributed processing of ECG and BP acquired data is performed. In the most interesting configuration, the PDA does the data acquisition, display and data communication while the main part of data processing is performed in a host laptop PC. Data communication is performed under an ad-hoc wireless network (802.11g).

Assessment of autonomic nervous system function in patients with non-alcoholic cirrhosis
Automatic dysfunction may contribute to the hemodynamic disturbances in cirrhosis. Tests of autonomic function were performed in 31 patients with non-alcoholic cirrhosis and 30 healthy subjects. Patients were divided into 3 groups according to child- Pugh,s classification ( A.B.C). The patients with moderate and severe cirrhosis( child B,C) had significant parasympathetic disturbance ( in the v...

Abstract Many studies have been conducted on heart rate variability. Variability in the heart signal of two sequential beats is called heart rate variability (HRV). Short- and long- term variability reflects autonomic nervous system function, so that increased or decreased heart rate variability (HRV) is an indicator of human health. So, the analysis of these changes can predict sudden death...

Autonomic nervous system dysfunction in diabetics can occur apart from peripheral sensorimotor polyneuropathy and sometimes leads to complaints which may be diagnosed by electrodiagnostic methods. Moreover glycemic control of these patients may prevent such a complications.Materials and Methods: 30 diabetic patients were compared to the same number of age and sex-matched controls regarding to e...
متن کاملEffect of Combined Exercise Training on Heart Rate Variability and Aerobic Capacity of Boys with Type 1 Diabetes
Background and Objective: Dysfunction in the autonomic nervous system can cause cardiovascular complications in patients with type 1 diabetes (T1D). The present study aimed to investigate the effect of combined exercise training on heart rate variability (HRV-5min), aerobic capacity (VO2max), and glycemic index in boys with T1D. Materials and Methods: In this semi-experimental research, 24 ado...
