HI Benjamin,

We do not currently have a published tutorial for external defibrillation. However, external defibrillation is functionally similar to ICD, the only difference is the geometry of the sources.  We have done this by generating a geometry in the shape of the paddle or pad to use in the model, placing the mesh to intersect the torso surface, calculating the intersection of the paddle mesh and the torso, then applying the sources to an element or two thickness based on the intersection.   The modules needed to do this are the same as used in the ICD example, except the GetDomainBounday module used to extract the torso surface (use a range 0 to 12 or the max value of the segmentation).  CalculateDistanceToFIeld can be used to with CalculateFieldData to assign the source values.  The rest is the same.  If you need more direction, I can walk you through the details.

cheers,
Jess
