The invention relates to a method for analysing an intracardiac electrogram (1), in particular for detecting a pulmonary vein (2) isolation status, via a control system (3), wherein the intracardiac electrogram (1) has been recorded at a, in particular predetermined, target region (4) via a catheter (5) inserted into a human body, wherein the catheter (5) comprises multiple electrodes (7), wherein multiple channels (10) of the intracardiac electrogram (1) have been recorded by, preferably between, the electrodes (7), wherein the electrodes (7) have a fixed order of placement on the catheter (5), wherein in an analysis routine (11), the control system (3) determines an electrical status of the target region (4) by analysing at least three of the channels (10). It is proposed, that the order of the electrodes (7) on the catheter (5) is provided to the control system (3) or saved in a memory (13) of the control system (3) and that in the analysis routine (11) the control system (3) determines the electrical status of the target region (4) based on spatial information including the order of placement of the electrodes (7) on the catheter (5).
