Assessment of Cardiovascular Risk in Assisted Living

Abstract

Disorders of the heart and blood vessels are the leading cause of health problems and death. Early detection of them is extremely valuable as it can prevent serious incidents (e.g. heart attack, stroke) and associated complications. This requires extending the typical mobile monitoring methods (e.g. Holter ECG, tele-ECG) by introduction of integrated, multiparametric solutions for continuous monitoring of the cardiovascular system. In this paper we propose the wearable system that integrates measurements of cardiac data with actual estimation of the cardiovascular risk level. It consists of two wirelessly connected devices, one designed in the form of a necklace, the another one in the form of a bracelet (wrist watch). These devices enable continuous measurement of electrocardiographic, plethysmographic (impedance-based and optical-based) and accelerometric signals. Collected signals and calculated parameters indicate the electrical and mechanical state of the heart and are processed to estimate a risk level. Depending on the risk level an appropriate alert is triggered and transmitted to predefined users (e.g. emergency departments, the family doctor, etc.).

Monitoring activities of daily living based on wearable wireless body sensor network

“…CardioNet is focused on diagnostics of patients with arrhythmias. There are examples of different wearable sensors to acquire diagnostic data [8][9][10][11][12][13][14].…”

Eye tracking within near-to-eye display

“…Moreover, the eye-tracking combined with smart glasses can be useful in many healthcare applications, e.g. for septic safe interaction for surgeons [10], for the elderly in ambient assisted living [11], navigation for blind persons [12], etc. The goal of this article is to investigate the potential of the gaze based interface for smart glasses.…”

Interactions using passive optical proximity detector

“…The hand gesture based touchless interactions with smart glasses can be useful in many healthcare applications, e.g. for septic safe interaction for surgeons [1], for the elderly in ambient assisted living [2], navigation for blind persons [3], etc.…”
