PROBLEM TO BE SOLVED: To perform appropriate treatment for a heart by accurately measuring impedances of leads embedded in a body.SOLUTION: Cardiac therapy equipment 1 includes an equipment main unit 4 and leads 3 that are detachably connected to the equipment main unit 4 and has electrodes 2 at leading ends, respectively. The equipment main unit 4 has: a pulse output section 6 that outputs a voltage pulse to the heart A via the electrodes 2 of the leads 3 a voltage measuring section 7 that measures a voltage value of the pulse output section 6 and a control section 8 that sets output conditions of the voltage pulse output from the pulse output section 6, on the basis of a ratio of the voltage values before and after the output of the voltage pulse with a predetermined pulse width in the pulse output section 6, measured by the voltage measuring section 7. The control section 8 sets the output conditions on the basis of a parameter computed by using the ratio defined as above in case a known impedance element is connected in place of the lead 3.COPYRIGHT: (C)2012,JPO&INPIT【課題】生体リードインピーダンスを精度よく測定して、心臓に対して適正な処置を行う。【解決手段】装置本体4と、該装置本体4に着脱可能に接続され先端に電極2を有するリード3とを備え、装置本体4に、リード3の電極2を介して心臓Aに対し電圧パルスを出力するパルス出力部6と、パルス出力部6における電圧値を測定する電圧測定部7と、電圧測定部7により測定されたパルス出力部6における所定パルス幅の電圧パルスの出力前後における電圧値の比率に基づいて、パルス出力部6から出力する電圧パルスの出力条件を設定する制御部8とを備え、該制御部8が、リード3に代えて既知インピーダンス素子を接続した際の比率を用いて算出したパラメータに基づいて出力条件を設定する心臓治療装置1を提供する。【選択図】図1
