Several skin preparation techniques are used in electrocardiogram (ECG) monitoring of horses. The objective of this study was to determine which methods produce the greatest signal quality using textile electrodes and standard silver/silver chloride (Ag/AgCl) electrodes.
Electrocardiogram data were collected using textile and Ag/AgCl electrodes simultaneously for 4 skin preparation techniques in 6 horses.
The effects of skin preparation (cleansing with isopropyl alcohol, with or without shaving the hair) and the effects of the application of a conductive gel were assessed using metrics of signal quality.
Shaving and cleansing with alcohol had no effect on signal quality for either electrode type. The Ag/AgCl electrodes contain a solid gel, and the application of additional gel did not affect signal quality. Data quality was significantly improved when gel was applied to textile electrodes. Furthermore, there was no difference in signal quality between electrode types when gel was used.
This study suggests that skin preparation by cleansing and/or shaving does not have a significant effect on equine ECG signal quality. When gel is used, textile electrodes are a practical alternative for Ag/AgCl electrodes, as they produce ECG recordings of the same quality.
在马的心电图（ECG）监测中使用了多种皮肤准备技术。本研究的目的是确定使用纺织电极和标准银/氯化银（Ag/AgCl）电极时，哪种方法能产生最佳的信号质量。
在6匹马中，同时使用纺织电极和Ag/AgCl电极，针对4种皮肤准备技术收集心电图数据。
使用信号质量指标评估皮肤准备（用异丙醇清洁，有无剃毛）的效果以及导电凝胶应用的效果。
对于两种电极类型，剃须并用酒精清洁对信号质量均无影响。Ag/AgCl电极含有固体凝胶，额外应用凝胶不会影响信号质量。当凝胶应用于纺织电极时，数据质量显著提高。此外，使用凝胶时，电极类型之间的信号质量没有差异。
本研究表明，清洁和/或剃须进行皮肤准备对马的心电图信号质量没有显著影响。当使用凝胶时，纺织电极是Ag/AgCl电极的一种实用替代方案，因为它们能产生相同质量的心电图记录。
