Zusammenfassung: | To provide systems, apparatuses and methods for detecting abnormal intra-cardiac activity.SOLUTION: Methods, apparatus and systems for medical procedures are disclosed herein and include detecting points of an intra-cardiac area that exhibits abnormal activation, such as local abnormal ventricular activation (LAVA). Points that exhibit such abnormal activation may be referred to as seed points that are identified during a first step of a process disclosed herein. The seed points may be identified using one or more inputs such as unipolar and bipolar mapping channels, body surface ECGs, past activation and neighboring points during the first step which prioritizes high specificity over sensitivity. The seed points may be identified using one or more inputs such as unipolar and bipolar mapping channels, body surface ECGs, past activation and neighboring points during the first step which prioritizes high specificity over sensitivity.SELECTED DRAWING: Figure 1
【課題】異常な心内活動を検出するためのシステム、装置及び方法を提供すること。【解決手段】医療処置のための方法、装置及びシステムが本明細書に開示されており、局所的な異常な心室興奮(LAVA)などの異常な興奮を示す心内領域の点を検出することを含む。このような異常な興奮を示す点は、本明細書に開示されるプロセスの第1の工程中に特定されるシード点と称され得る。シード点は、感度よりも高特異性を優先する第1の工程中に、単極及び双極マッピングチャネル、身体表面ECG、過去の興奮、隣接点などの1つ又は2つ以上の入力を使用して特定されてもよい。シード点は、感度よりも高特異性を優先する第1の工程中に、単極及び双極マッピングチャネル、身体表面ECG、過去の興奮、隣接点などの1つ又は2つ以上の入力を使用して特定されてもよい。【選択図】図1 |
