Summary:To provide medical apparatus and methods for diagnostic and site determination of cardiac arrhythmias within a heart of a subject.SOLUTION: A computing device receives, records and processes electrocardiogram (ECG) signals in the form of bipolar and unipolar ECGs associated with respective cardiac tissue locations corresponding to catheter distal end sensors on locations. Unipolar ECGs that include signals from a plurality of successive heartbeats corresponding to locations within an area of study are analyzed to identify Fractionated Unipolar ECG Signal Complexes (FUESCs) of unipolar ECGs by defining complexes of the unipolar ECGs that correspond to respective bipolar activity windows. Identified arrhythmia sites for treatment include a predetermined number of unipolar ECGs that have a predetermined number of FUESCs. Atrial arrhythmia sites for treatment by ablation can be identified with respect to FUESCs of unipolar ECGs that include signals from at least 10 successive heartbeats of an atrial tissue study area.SELECTED DRAWING: Figure 1 【課題】対象の心臓内の心不整脈の診断及び部位判定のための医療装置及び方法を提供すること。【解決手段】コンピューティングデバイスは、場所上のカテーテル遠位端センサに対応するそれぞれの心臓組織の場所に関連付けられた双極及び単極ECGの形態で心電図(ECG)信号を受信、記録、及び処理する。調査領域内の場所に対応する複数の連続する心拍からの信号を含む単極ECGを分析して、それぞれの双極活性ウィンドウに対応する単極ECGの複合体を定義することによって、単極ECGの分画単極ECG信号複合体(FUESC)を識別する。治療のために識別された不整脈部位は、所定の数のFUESCを有する所定の数の単極ECGを含む。アブレーションによる治療のための心房不整脈部位は、心房組織調査領域の少なくとも10回の連続心拍からの信号を含む単極ECGのFUESCに関して識別することができる。【選択図】図1
