073_16840-D1 A Novel 2-D Spatial-Temporal ECG Representation Using Multipolar Esophageal Catheters: A Pilot Study

P-waves in surface ECGs are often of minor quality and lead to uncertainties in non-invasive arrhythmia diagnostics. We therefore exploited the advantages of esophageal ECGs (eECG) to improve the diagnosis of atrial arrhythmias. Esophageal ECGs of 14 patients with supraventricular arrhythmias and 6
