Three cases of allergic contact dermatitis localized to the sites of electrocardiograph‐monitoring electrodes are reported. All patients had positive patch tests to both the gel and the adhesive part of the Red Dot ® 2239 3M™ monitoring electrode used and to the p ‐ tert ‐butylphenol‐formaldehyde resin (PTBP‐F‐R) of the standard series. Two patients had a history of possible exposition to the resin previously but there was no explanation for the third. No information about the presence of PTBP‐F‐R in the electrodes could be obtained from the manufacturers. Chemical analysis of samples of the electrode, using a gas chromatography‐mass spectrometry (GC‐MS) and high pressure liquid chromatography (HPLC) analytical system, demonstrated the presence of several PTBP‐F‐R derivatives in both the gel and the adhesive part.
