Description
Summary:Textile capacitively-coupled (CC) electrodes have the potential of being integrated into home textiles to realize long-term cardiac surveillance, since they are more comfortable and convenient than conventional contact electrodes. Previous study mainly focused on the measurement performance of CC-based electrocardiogram (ECG) devices, but the diagnostic value of these novel devices, such as capability of supporting preliminary arrhythmia diagnosis, has not been investigated comprehensively. In this study, we proposed a CC-based ECG cushion and assessed measurement performance and diagnostic value by a clinical test on 4 healthy people and 7 arrhythmia patients. In addition to precise measurement of critical ECG structures (true positive rate of R waves: 0.994±0.006, mean absolute error of RR intervals: 1.690±1.331 ms), the proposed cushion can provide valuable information, comparable with the Holter, for cardiologists to distinguish the normal beats, ventricular beats and premature supraventricular contractions during long-term monitoring. In conclusion, the proposed cushion is verified to provide enough signal details for preliminary diagnosis of arrhythmia, as a promising system for disease screen and danger alarm of arrhythmia in certain scenario of long-term cardiac surveillance at home.
