Study of Materials for Manufacturing Electrodes Designed for Long-Term Registration of Electrocardiogram

Electrocardiography is an important diagnostic method that allows assessing the electrical activity of the heart. Its use allows diagnosing cardiovascular diseases at early stages, preventing their progression and development of complications. However, not all pathologies can be detected during a short-term study. If the presence of such dis eases is suspected, a method of long-term recording of the electrocardiogram is used. The quality of its recording during long-term recording largely depends on the electrodes used. Today, the most common are electrodes with silver chloride coating, showing good results for a short time. However, their use for more than 24 hours leads to signal distortion and irritation of the patient’s skin due to dehydration and surface degradation. The article pre sents the results of studies of materials intended for the manufacture of dry electrodes, their properties and influence on the indicators obtained during the examination.
