väliselektroodide

Väliselektroodid refers to external electrodes used in various medical and scientific applications. These electrodes are typically applied to the surface of the skin to detect, record, or stimulate electrical activity. Common uses include electrocardiography (ECG) for measuring heart electrical activity, electroencephalography (EEG) for brain activity, and electromyography (EMG) for muscle activity. In these contexts, väliselektroodid are essential for non-invasive monitoring and diagnosis.

The design and material of väliselektroodid vary depending on their intended use. They are often made from conductive materials like silver/silver chloride, which provide a stable electrical interface with the skin. Adhesive backing is frequently used to ensure secure placement during procedures. Proper skin preparation, such as cleaning and sometimes abrading the skin surface, is crucial for obtaining clear and accurate signals from these external electrodes. The placement of väliselektroodid follows standardized protocols to ensure consistent and comparable readings across different individuals and examinations. They are a fundamental component in a wide range of diagnostic tools.
