An electromedical implant for monitoring a thoracic property of a living being is provided that includes a detector arrangement including an impedance measuring unit and an electrode arrangement, which are equipped to capture a measurement signal associated with the thoracic property in the form of an impedance signal a monitoring arrangement, which is connected to the detector arrangement and equipped to generate a parameter from the measurement signal that is indicative of the thoracic property, and an evaluation unit, which is connected to the monitoring arrangement and equipped to determine an evaluation result regarding the thoracic property based on the parameter. According to the invention, the electrode arrangement comprises at least a plurality of mutually isolated electrodes, which are disposed on the housing and operatively connected by way of the impedance measuring unit and which can be separately controlled, wherein an electrode body has a strip shape.
