ECG gel, also known as electrode gel or conductive gel, is a specially formulated substance designed to enhance the conductivity between the skin and the electrodes during ECG procedures. This gel is applied to the skin at the electrode placement sites to reduce impedance and improve the transmission of electrical signals from the body to the ECG machine. ECG gel plays a crucial role in achieving accurate and reliable electrocardiographic recordings. Its conductivity-enhancing properties, ability to reduce artifacts, and promotion of skin hydration contribute to the overall effectiveness of ECG procedures. Healthcare professionals should carefully choose high-quality ECG gel to optimize diagnostic accuracy and enhance patient comfort during electrocardiography.
