Abstract:
1. A stimulation arrangement, comprising: a stimulation unit to deliver electrical stimulation pulses for stimulating body tissue; and an evaluation unit to receive at least one electrical signal in conjunction with the delivery of a stimulation pulse and to evaluate said received electrical signal for checking both stimulation success and lack of stimulation success, and wherein the evaluation unit is capable of detecting first signal features in the received electrical signal that characterize a case of lack of stimulation success, and delivering a corresponding first output signal, and wherein the evaluation unit is capable of detecting second signal features in the received electrical signal that characterize a case of stimulation success, and delivering a corresponding second output signal; and wherein the evaluation unit associates the received signal with a stimulation pulse in respect of time and detects a feature of a polarization artifact as a signal feature in the received electrical signal.
