In-vivovalidation of a new non-invasive continuous ventricular stroke volume monitoring system in an animal model

Table 1 Electrode positions, rendered as coordinates (X, Y) on the thoracic skin of the animal

Electrode #	Position X (in mm) Horizontal position (left-right) with respect to Gauge Point (GP). Orientation: The left-lateral side of the thorax has positive X values	Position Y (in mm) Vertical position (cranial-caudal) with respect to Gauge Point (GP). Orientation: The cranial end of the thorax has positive Y values

The 2D positions of the electrodes are defined as relative distances with respect to the Gauge Point (GP). These relative distances are rendered as displacements in the horizontal direction (X, left-right) and the vertical direction (Y, cranial-caudal), respectively, as measured along the (curved) thoracic skin. These nine electrodes can be applied conveniently using a single compound electrode sticker, in which all electrodes are at their correct relative positions with respect to each other.
