The invention relates to an electrode patch (10, 10'), in particular for performing electrocardiography. The electrode patch (10, 10') comprises an elastic adhesive layer (12, 12') having an adhesive contact surface (14, 14') that is configured to adhere to the skin of a subject the electrode patch (10, 10') is applied to； an elastic conductive layer (26, 26') including a plurality of measurement points (26A) and conductive paths (26B), the conductive paths (26B) being configured to conductively connect the plurality of measurement points (26A) to a connector (32)； and a plurality of electrodes, wherein each of the plurality of electrodes is formed at least by one of the plurality of measurement points (26A) and a corresponding recess (28) provided in the adhesive layer (12, 12'), which recess (28) extends through the entire layer thickness of the adhesive layer (12, 12') and is provided or providable with a substance (30, 30') that is adhesive and conductive, such as hydrogel, so as to conductively connect the one of the plurality of measurement points (26A) to the skin of the subject. At least 90% of the area of the electrode patch (10, 10') is radiolucent by means of radiolucency of the adhesive layer (12, 12') and the conductive layer (26, 26').
