Method for detecting a cardiac isolation status of a measurement location in the presence of far field interference

Abstract

The invention concerns a method for determining a cardiac isolation status of a measurement location (1) in the presence of far field interference by analysing a multi-channel intracardiac electrogram (2) of the measurement location (1) via a control system (3), wherein in an identification routine (9) the control system (3) applies an activation search algorithm to analysis windows (10) of at least 400 ms in at least two different channels (11) of the intracardiac electrogram (2), wherein the activation search algorithm identifies windows (W) of local activation potentials (12) inside of the analysis windows (10), wherein in a classification routine (15) the control system (3) analyses the local activation potentials (12) to determine the cardiac isolation status of the measurement location (1).
