Summary:To provide identification of a tissue having abnormal electrophysiological potentials.SOLUTION: An apparatus consists of a catheter that is configured to be inserted into a chamber of a heart and that has one or more electrodes configured to contact a myocardial tissue at multiple locations in the chamber. The one or more electrodes receive electrical signals responsive to a conduction wave traveling through the tissue. The apparatus includes a display and a processor that is configured to receive the electrical signals from the catheter and to render to the display, responsively to the electrical signals, a map of the chamber including an indication of local times of occurrence of the conduction wave at the multiple locations. The processor is also configured to calculate, responsively to the local times of occurrence, a velocity of the conduction wave between the locations and to mark on the map one or more areas of the chamber in which the velocity is below a preset threshold.SELECTED DRAWING: Figure 1 【課題】異常な電気生理学的電位を有する組織を識別すること。【解決手段】装置であって、心臓の室に挿入されるように構成されたカテーテルであって、室内の複数の位置において心筋組織に接触するように構成された1つ又は2つ以上の電極を有する、カテーテルから構成される、装置。1つ又は2つ以上の電極は、組織を通って進行する伝導波に応答する電気信号を受信する。装置は、ディスプレイと、カテーテルから電気信号を受信するように、かつディスプレイに、電気信号に応答可能に、複数の位置における伝導波の局所的な発生時刻の指標を含む室のマップをレンダリングするように、構成されたプロセッサと、を含む。プロセッサはまた、局所的な発生時刻に応答可能に、位置間の伝導波の速度を計算し、マップ上に、速度が事前設定された閾値未満である、室の1つ又は2つ以上の区域をマークするように、構成される。【選択図】図1
