Device for determining impedance of the thorax

摘要

The implant has electrodes connected with an impedance measuring unit (140) and a measuring signal generator (130). The impedance measuring unit measures the voltage between the electrodes after the elapse of the different lengths of time spans that begin at the starting of delivery of the current pulse and end before the ending the delivery of the current pulse. A voltage value representing the measured voltage is provided. An independent claim is also included for a thorax impedance determination system comprising an electromedical implant.
