How does wearing lotion affect EKG?

Wearing lotion can potentially affect an EKG (electrocardiogram) by interfering with the electrical signals being measured. Lotions, especially those with metallic components or high moisture content, can create a barrier between the skin and the electrodes, leading to poor contact and potentially causing artifacts or noise in the EKG readings. This may result in inaccurate interpretations of the heart's electrical activity. Therefore, it is generally advised to avoid applying lotion to areas where electrodes will be placed before an EKG.
