The shrubbery possible medical equipment which has the induction switching regulator which includes the inductor which has the ferromagnetic magnetic core is stated. The aforementioned equipment seems that it occurs with MRI scan, the magnetic core saturation detector in order to inspect the saturation of the magnetic core of the inductor which shows the existence of the magnetic field is installed. The aforementioned equipment is formed in order the occasion where magnetic core saturation is inspected, to change behavior by among other things for example entering into MRI mode. MRI mode stop and fixed rate removal pulse peshingu of remedy, and/or can include the nullfication of pulse characteristic arrhythmic remedy.< Selective figure >Figure 1強磁性磁心を備えたインダクタを含む誘導スイッチングレギュレータを備えた植え込み可能な医療機器を記載する。前記機器は、MRIスキャンによって生じるような、磁場の存在を示すインダクタの磁心の飽和を検知するための磁心飽和検知器を組み込む。前記機器は磁心飽和を検知した際に、例えばMRIモードに入ることなどによって、振る舞いを変えるように構成される。MRIモードは治療の停止、定率除脈ペーシング、および/もしくは頻脈性不整脈治療の無効化を含み得る。【選択図】図1
