Abstract

An evaluation of motion artefact for a newly CE approved wireless bodyworn monitoring device is presented. This evaluation has shown that the system under test has greatly reduced motion artefact with comparison to an FDA-approved leaded system. Analysis of physiological data, such as quality of ECG signal, accuracy of recording of heart rate, temperature and ECG R-R interval has shown the system to offer high fidelity recordings and a robust service during a range of basic movements.Presented results have shown that the average difference in heart rate between the prototype and the reference device was 3.8bpm with standard deviation of 12.4bpm. Temperature analysis indicated the average difference between the prototype and the reference device was 5.66oC, with standard deviation of 0.44oC. R-R interval analysis highlighted mean interval difference as 78.96ms with standard deviation of 123.1ms. In general, the user activity of bending had highest errors due to the considerable torso movement.
