Description
〔背景技術〕
不整脈は、生命を維持する心臓の血液ポンピング作用を妨害する心調律の異常である。不整脈の例には、心室性頻脈および心房性頻脈がある。心室性頻脈は下側の心腔すなわち心室で生じ、心房性頻脈は上側の心腔すなわち心房で生じる。心室性頻脈は、心室内で始まる、3回以上の連続した心室性期外収縮を特徴とする速い心拍である。心室性頻脈は、心臓が体中に十分な血液をポンピングできなくなる可能性があるため、致命的となる可能性がある不整脈である。Medtronic社等の企業は、心室性頻脈が検出された場合に、心室ペーシングパルスを心臓に送出することによって心室性頻脈を上手く処置するために用いることができる埋め込み可能ペースメーカを開発している。
[発明の概要]
本発明は、他の方法では不整脈を検出するためのウィンドウがかなり短くなる、ペーシングレートが高いペーシングの状況、および/または不整脈を検出するための長いウィンドウを維持するために遅いペーシングレートを受け入れなくてはならないペーシングの状況に特に役立つ改良された心臓ペーシング方法を提供する。

TLRIをDVAIとPAVの和に等しく設定する手段(514)と、
を備え、
前記チェックする手段、前記PAVを設定する手段、および前記TLRIを設定する手段は、該ソフトウェアシステムを作動論理により制御する、
