Fig. 6From: Semi-supervised clustering of fractionated electrograms for electroanatomical atrial mapping Clustering scatter plots and electroanatomical maps for three patients (DB2): a– c 3D scatter plots for each patient of the most relevant features: \(\xi _2\), \(\xi _7,\) and \(\xi _8\). Clusters are represented by colors and resembles the structure in all three examined patients. d– f: View of the posterior wall of the left atrium. The clustering results are used to display an electro-anatomical maps for each patient. The maps show the distribution of reconstructed EGM patterns over the atrium. Critical sites with hith level of fractionation are color coded in red Back to article page
