The purpose of applying paste or jelly when running anEKG (Electrocardiogram)is toreduce skin resistance. This conductive gel ensures better conductivity between the skin and the electrodes, resulting in a clearer and more accurate recording of the heart's electrical activity. Without the gel, poor contact can lead to high resistance and artifacts in the EKG trace.
