Electrocardiography is the measurement of the heart’s activity as an electrical signal. The heart pumps blood throughout the body by contracting and relaxing its muscles. During this process, the heart produces electrical signals. Detecting and recording these signals helps evaluate heart function and identify abnormalities. For example, it can reveal issues with heart rate and rhythm, aiding in the diagnosis and treatment of heart disease. Electrocardiography is performed using devices such as electrocardiographs (ECGs) and Holter monitors, which are commonly used in medical settings.
Electrocardiograph electrodes are used to measure these signals. These electrodes are small conductive pads or probes that attach to the skin. They accurately detect the heart’s electrical signals and transmit them to the ECG device. Typically, several electrodes are placed at different spots on the body to get a comprehensive recording of the heart’s activity. These electrodes are secured to the skin with a special gel or adhesive to ensure a clear signal. Electrocardiograph electrodes are essential for healthcare professionals to assess heart health and play a crucial role in safe and accurate diagnosis.
Silver chloride electrodes are mainly used as the electrode elements. These electrodes are preferred because they have a lower polarization voltage compared to other types, making them more efficient at capturing the heart’s electrical signals from the skin’s surface.
