A less resistant and better conducting layer, the dermis, lies beneath the epidermis. The dermis is composed of living cells and is the layer of skin needed to detect electrical signals forthe ECG. For adequate electrode contact, dead skin, hair, oil, and any other deterrent or resistance to conductivity must be removed. Providing an electrode-to-skin interface is crucial for detection of electrical signals fromthe heart. The following skin preparation techniques should be used on all individuals: I Shave any chest hair, where appropriate, from each electrode site.
