Method for detecting state of cardiac isolation of measurement location in presence of far-field interference

The invention relates to a method for determining the cardiac isolation state of a measurement location (1) in the presence of far-field interference by analyzing a multi-channel electrocardiogram (2) of the measurement location (1) via a control system (3), the control system (3) applies an activation search algorithm to an analysis window (10) of at least 400 ms in at least two different channels (11) of the electrocardiogram (2), where the activation search algorithm identifies a window (W) of local activation potentials (12) inside the analysis window (10), where, in a classification routine (15), the local activation potentials (12) of the analysis window (10) are classified by the activation search algorithm. The control system (3) analyzes the local activation potential (12) to determine the cardiac isolation state of the measurement location (1). 本发明涉及一种用于在存在远场干扰的情况下通过经由控制系统(3)分析测量位置(1)的多通道心脏内电图(2)来确定所述测量位置(1)的心脏隔离状态的方法，其中，在识别例程(9)中，所述控制系统(3)将激活搜索算法应用于所述心脏内电图(2)的至少两个不同通道(11)中至少400ms的分析窗口(10)，其中，所述激活搜索
