上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、データセットのヒストグラムを表示することは、円形ヒストグラムを表示することを含む。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、代表メトリック値は、期間にわたって複数の電極の各々について生成される。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態は一つ以上のメトリックインジケータを含み、メトリックインジケータは一つ以上の代表メトリック値に対応する。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、データセットの代表メトリック値は、データセットの標準偏差、エントロピー、尖度、歪度および円形平均のうちの少なくとも一つを含む。
別の例示的な医療装置は、心臓の電気的活動をマッピングするためのシステムを含む。該システムは、複数の電極を備えたカテーテルシャフトを含む。該システムはまた、プロセッサを含む。プロセッサは、複数の電極のうちの少なくとも一つから一組の信号を収集することができる。一組の信号は期間にわたって収集される。プロセッサはまた、一組の信号から少なくとも一つの伝搬ベクトルを算出し、少なくとも一つの伝搬ベクトルからデータセットを生成し、データセットの統計分布を生成し、統計分布の視覚的表現を生成することができる。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、データセットのヒストグラムを表示することは、円形ヒストグラムを表示することを含む。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、代表メトリック値は、期間にわたって複数の電極の各々について生成される。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態は一つ以上のメトリックインジケータを含み、メトリックインジケータは一つ以上の代表メトリック値に対応する。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、データセットの代表メトリック値は、データセットの標準偏差、エントロピー、尖度、歪度および円形平均のうちの少なくとも一つを含む。
上述の実施形態の代わりに、またはこれに追加して、別の実施形態において、データセットを生成する工程は、少なくとも一つのベクトル角度に対して統計分析を実行することをさらに含む。
明確な指示の有無にかかわらず、すべての数値は本明細書において「約(about)」という用語によって修飾されているものとみなす。用語「約(about)」は一般に、当業者が記載値と等しい(例えば、同等の機能または結果が得られる)と考えるであろう数値の範囲を指す。多くの場合、用語「約(about)」は、最も近い有効数字に四捨五入された数値を含むことができる。
本明細書および添付の特許請求の範囲で用いられるように、用語「一つの(a,an,the)」等の単数形は、別段の明確な指示がない限り、複数の対象を含む。本明細書および添付の特許請求の範囲で用いられるように、用語「AまたはB(or)」等は一般に、別段の明確な指示がない限り、「AおよびBの少なくとも一方(and/or)」を含む意味で用いられる。
例えば、処理システム32は電極24のうちの一つ以上について活性化時間を収集すると、サンプリングされた時間間隔にわたって電極24のうちの一つ以上から収集した各活性化時間についての(大きさおよび角度を含む)伝搬ベクトルを決定することができる。例えば心房細動の間、所与の電極24は所与のサンプリング期間(例えば、30〜40秒)の間に200〜300の活性化時間を収集することができ、その結果、処理システム32は200〜300の拍に対応する200〜300の(大きさおよび角度を含む)伝搬ベクトルを決定することができる。上述のように、伝搬ベクトルは細胞の波面の伝搬についての大きさおよび方向を含んでいてもよい。伝搬ベクトルの大きさは、速度、逆速度、信頼度または他の関連尺度を表していてもよいことが企図される。この大きさはまた、固定値に設定することもできる。さらに、細胞の波面の伝搬についての方向(例えば、伝搬角度)および速度は、伝搬ベクトルを決定する対象となる電極と隣接する電極によって検出された活性化時間を比較することによって決定することができる。例えば、処理システム32はベクトルの伝搬角度を決定するために、円形平均を利用することができる。伝搬ベクトルおよび伝搬の局所的方向を決定する方法については、「ベクトル場を用いた電気生理学的マッピングの間の活動パターンの表示および特定(Representation and Identification of Activity Patterns during Electro−physiology Mapping Using Vector Fields)」と題される米国特許出願第61−823386号に開示されており、この開示はその全体が参考として取り入れられている。
