    • Bidomain Simulations of Subendocardial Ischemia: The Forward and Inverse Problems 

      Lysaker, Ola Marius; Nielsen, Bjørn Fredrik; Wall, Samuel (Journal article; Peer reviewed, 2014-09)
      We provide an analysis of the bidomain theory in relation to anterior subendocardial ischemia. Using the static bidomain model, this analysis explains why simulations often do not produce ST depression when the ischemia ...

    • Computing Ischemic Regions in the Heart: On the Use of Internal Electrodes 

      Lysaker, Ola Marius; Nielsen, Bjørn Fredrik; Wall, Samuel (Conference object; Peer reviewed, 2013-09)
      In order to better locate ischemic regions in the heart using electrical measurements and inverse solutions, we explore the possibility for supplementing BSPM data sets with additional internal electrodes in the esophagus. ...

    • Observability of Ischemia and the Need for Patient Specific Geometrical Models in Inverse ECG. 

      Lines, Glenn Terje; Lysaker, Ola Marius; Nielsen, Bjørn Fredrik (Journal article; Peer reviewed, 2013-09)
      We have performed ECG simulations on four realistic geometries in order to quantify the effect of ischemic location in the left ventricle in terms of ST shifts in the body surface potential (BSP). Using 64 electrodes we ...
