AB  - Non-invasive imaging of cardiac electrophysiology provides a non-invasive way of 
      obtaining information about electrical excitation. An iterative algorithm based 
      on a general regularisation scheme for non-linear, ill-posed problems in Hilbert 
      scales was applied to the electrocardiographic inverse problem, imaging the 
      ventricular surface activation time (AT) map. This method was applied to 
      electrocardiographic data from a 31-year-old healthy volunteer and a 24-year-old 
      patient suffering from a Wolff-Parkinson-White (WPW) syndrome. The objective was 
      to evaluate non-invasive AT imaging of an autonomous sinus rhythm and to quantify 
      the localisation error of non-invasive AT imaging by localising the accessory 
      pathway of the WPW syndrome and a pacing site for left ventricle pacing. The 
      distances between the invasive and non-invasive localisation of the pacing site 
      and the accessory pathway were 8 mm and 5 mm. The clinical case presented, shows 
      that this non-invasive AT imaging approach may enable the reconstruction of 
      single focal events with sufficient accuracy for potential clinical application.
