Method for analysing an intracardiac electrogram via a control system, wherein the intracardiac electrogram has been recorded, in particular during ablation therapy, via a catheter inserted into a human body and has a time length, wherein the catheter comprises multiple electrodes placed at different anatomical positions, wherein multiple channels of the intracardiac electrogram have been recorded by the electrodes, wherein the control system groups the channels into at least a first group of channels comprising at least one channel assigned to a first anatomical region and a second group of channels comprising at least one channel assigned to a second anatomical region, wherein the control system derives derived features comprising a first derived feature relating to the first anatomical region and a different second derived feature relating to the first anatomical region from the first group of channels and derives the first derived feature and the second derived feature relating to a second anatomical region from the second group of channels, wherein the control system derives data points of the derived features in intervals over the time length, the first and second features thereby each having a time dimension and a value dimension with a value range, characterized in that the control system combines the derived features into a feature space comprising at least an anatomical dimension and a feature dimension and a time dimension and an intensity dimension, that the anatomical dimension comprises the anatomical regions, that the feature dimension comprises the derived features, that the time dimension is the time dimension of the first and the second derived features, that the intensity dimension comprises an intensity range, that the control system transforms the value ranges of the derived features onto the intensity range, that the control system comprises a display, and, that the control system displays on the display the at least, preferably exactly, four dimensions of the feature space, and/or, that the control system uses the feature space to derive a prognosis about the success of the ablation therapy and/or to derive a proposal for a next step in the ablation therapy and/or to derive a prognosis of the change of the feature space by a possible ablation step, and, that the control system transforms the value ranges of the derived features onto the intensity range via a different transformation function per feature. wherein the control system derives derived features comprising a first derived feature relating to the first anatomical region and a different second derived feature relating to the first anatomical region from the first group of channels and derives the first derived feature and the second derived feature relating to a second anatomical region from the second group of channels, wherein the control system derives data points of the derived features in intervals over the time length, the first and second features thereby each having a time dimension and a value dimension with a value range, characterized in that the control system combines the derived features into a feature space comprising at least an anatomical dimension and a feature dimension and a time dimension and an intensity dimension, that the anatomical dimension comprises the anatomical regions, that the feature dimension comprises the derived features, that the time dimension is the time dimension of the first and the second derived features, that the intensity dimension comprises an intensity range, that the control system transforms the value ranges of the derived features onto the intensity range, that the control system comprises a display, and, that the control system displays on the display the at least, preferably exactly, four dimensions of the feature space, and/or, that the control system uses the feature space to derive a prognosis about the success of the ablation therapy and/or to derive a proposal for a next step in the ablation therapy and/or to derive a prognosis of the change of the feature space by a possible ablation step, and, that the control system transforms the value ranges of the derived features onto the intensity range via a different transformation function per feature.
