Figure 5 Antero-posterior (top row) and postero-anterior (lower row) views the left atrium showing the density and distribution of localised irregular activation, localised rotational activation and focal firing (red=no occurrences, purple=highest density) in patient 10. Each pair of images represent 2 sequential 30s maps. Graphs below represent correlation plots for each anatomy vertex (1st map X axis, 2nd Y axis) with R2 for LIA 0.92, LRA 0.39 and FF 0.49. Inset graph shows correlation for regions with FF frequency ≥1 every 3s on the first map with R2 of 0.74.
