Ambulatory blood pressure monitoring (ABPM) devices provide 24-hour profiles of mean arterial pressure (MAP) and heart rate (HR) by inflating an arm-cuff every 15 minutes during daytime and every 20 minutes during night-time. Aim of this work is to evaluate whether the intrinsic structure of ABPM dynamics can be described during day and night subperiods by calculating the fractal dimension (FD) of...
The ability of accurate measuring of cardiac output (CO) in clinical medicine is important as it is provided for improved diagnosis of abnormalities, and can be used to guide the appropriate management. Estimation of cardiac output from arterial blood pressure (ABP) waveforms has received considerable attention in recent years. So far, various estimation methods are used for the measurement of CO...
Modern QRS detectors in patient monitoring systems must provide accurate results even when interfering noise is present. This task is complicated by the heterogeneous and non-uniform nature of the patient population. Certain beat morphologies demand a significant increase in the complexity of beat detection algorithms. At the same time, it is important to take a system-wide approach to the beat detection...
Health monitoring and body area network (BAN) applications require wireless intelligent monitoring devices and information systems. The aim of our research is to propose a prototype of wearable wireless monitoring device optimized to supervising the patient and examine the influence of movement on the heart rate during normal daily activities. Main purpose of the proposed system consists in simultaneous...
The early detection of myocardial ischemia is an essential lever for its successful treatment. We investigated an ECG monitoring system with 3 electrodes. Optimal electrode positions are determined using a cellular automaton. The spatially heterogeneous effects of myocardial ischemia were modeled by altering 4 electrophysiological parameters: action potential amplitude and duration, conduction velocity...
For the practical research on influences of vascular diseases on the cardiovascular system a torso model is developed that represents all major arteries and veins. The model allows analysing the reaction of vascular diseases on the time-dependant variance of pressure and volume flow distribution. Therefore the passages between arterial and venous vessels are equipped with flow sensors and pressure...
In this paper, we explore the feasibility of integrating data gleaned from home-based sensors and information from self reporting to support the self-management of Chronic Heart Failure. Time spent sleeping, television usage and utility usage were recorded by sensor based technology within the home environment for one participant over a 30 day period. Information in relation to a participant's daily...
