摘要:
An electrode unit for carrying current or voltage between an implantable electromedical device and a treatment and/or diagnosis site in the human body comprises at least one current-/voltage-carrying feed line (1) and at least one electric contact pole to the body part. The feed line (1) is associated with at least one section (4) having frequency-dependent transmission behavior, wherein this at least one frequency-dependent transmission section (4) at least partially filters out therapeutically and/or diagnostically undesirable signals in at least one defined frequency range.

摘要:
A signal processing apparatus is disclosed comprising an input stage for the preparation of a physiological signal, in particular an electrocardiogram, which is adapted to provide a signal of an alternating polarity, which is formed from the physiological signal and which is to be evaluated, and is connected to an evaluation stage for forwarding of the signal to be evaluated, wherein the evaluation stage is adapted to respond to a reference moment in time associated with the physiological signal, and for at least one signal segment, associated in respect of time with the reference moment in time, of the signal to be evaluated, to detect a respective amplitude value for at least some characteristic curve points contained in the signal segment such as signal maxima and minima, inflection points and so forth and to generate from the amplitude values obtained in that way a morphology code which describes the form of the respective signal segment.
摘要:
An implantable medical device, which is connected or is to be connected to at least two elongated electric function conductors for the transmission of treatment signals or diagnostic signals or both, and at least one electrode pole connected to at least one of the function conductors, via which electrode pole electric current can be delivered in the case of use to surrounding tissue of the body or with which electric potentials can be sensed in the surrounding tissue or both.
