An electrode transfers electrical signals from the skin to the ECG device. Electrodes used on multiple patients may become dirty or worn. Dirty or worn electrodes cannot transmit signals. Dirty or worn electrodes can prevent the ECG from detecting the patient’s heartbeat. Electrodes eventually need to be replaced. Replacement ECG electrodes can be fabricated from simple materials.en-USElectricalUMDNS: 11407ECGBTA SkillsArticle
