The electrodes shirt design for ECG imaging

Electrocardiographic imaging (ECGI) is a non-invasive technique for reconstructing cardiac electrical activity from body surface electrocardiogram (ECG) signals. The collection of ECG signals from the body surface is a vital stage in ECGI. Placing and fastening electrodes in conventional ECG electrode acquisition equipment is a time-consuming and complex process. It is not uncommon for the acquired signal to be of poor quality or to be completely absent due to insufficient contact between certain electrodes and the surface skin. The study recommends the development of a novel electrode shirt for ECGI. The electrode shirt optimizes the multi-channel ECG acquisition efficiency; the electrode holders aid in the selection and adjustment of electrode placements flexibly; and the elasticity of the fabric and the presence of airbag columns ensures optimal skin-to-electrode contact. About 280 body surface ECG signals of 16 male volunteers were analyzed in this study. The electrodes shirt described above achieves optimal signal quality in a variety of body shapes with no electrodes slipping off.
