Summary:To provide a system for ablating tissue.SOLUTION: Described embodiments include an apparatus, including a display and a processor. The processor is configured to navigate a catheter to a particular location within a body of a subject, using each of a plurality of electrodes coupled to the body of the subject. The processor is further configured to subsequently identify, from a signal that represents an impedance between a given pair of the electrodes, that a phrenic nerve of the subject was stimulated by a pacing current passed from the catheter into tissue of the subject at the particular location, and to generate an output on the display, in response to the identification. Other embodiments are also described.SELECTED DRAWING: Figure 1 【課題】 組織をアブレーションするためのシステムを提供すること。【解決手段】 記載される実施形態は、ディスプレイとプロセッサとを含む装置を含む。プロセッサは、対象の身体に接続された複数の電極のそれぞれを使用して対象の身体内の特定の位置までカテーテルを誘導するように構成されている。プロセッサは更に、その後、特定の位置にカテーテルから対象の組織に流されたペーシング電流によって対象の横隔神経が刺激されたことを、電極の特定の対の間のインピーダンスを表す信号から特定し、かつ、その特定に応じてディスプレイ上に出力を発生するように構成されている。他の実施形態も記載する。【選択図】 図１
