The present invention relates to an apparatus for medical applications. The apparatus includes an oblong conductive element having a distal end. A resistance element is disposed in the vicinity of the distal end. The resistance element changes the resistance thereof as a function of a temperature and/or an electromagnetic field. To this end, the resistance element is designed to reduce a temperature rise of the distal end caused by energy absorption from, for example, an electromagnetic field.

An exemplary implantable medical device includes an electrode lead connector having at least one electrical contact for connection of an electrode lead, and an analyzing unit which is connected to the electrode lead connector and is designed to detect and evaluate a response signal present at the at least one electrical connector in response to known electromagnetic irradiation. The analyzing unit may compare a signal modulation resulting from an electromagnetic irradiation of the electrode lead with a reference signal modulation. The electrode lead may be classified as defective if the deviation exceeds a threshold deviation. If a second antenna is available, the analyzing unit may compare response signals resulting from electromagnetic irradiation of the electrode lead and the second antenna. If the ratio of response signals exceeds a threshold, the electrode lead may be classified as defective.

An implantable electronic therapy device, having a therapy unit, a heart rate capturing unit, a contractility determination unit, and an evaluation and control unit. The therapy unit delivers an antitachycardiac therapy. The heart rate capturing unit determines a ventricular heart rate from an input signal, and the contractility determination unit generates from an input signal, a contraction signal reflecting a contractility of a ventricle. The evaluation and control unit is connected to the therapy unit, the heart rate capturing unit, and the contractility determination unit actuates the therapy unit to administer an antitachycardiac therapy when the heart rate capturing unit detects an increase in the heart rate above a specified threshold value and the contractility determination unit supplies a contraction signal which is not physiologically adequate for the increase in the heart rate.
