1. A system, comprising:
memory to store instructions and data, the data comprising:
electrical data representing electrical signals measured on a body surface for at least one time interval; and
geometry data representing a primary geometry of a cardiac envelope, including nodes distributed across the cardiac envelope, and a geometry of the body surface including measurement locations for the electrical signals measured on the body surface;
a processor to access the memory and execute the instructions that, when executed by the processor, cause the processor to at least:
perturb the primary geometry of the cardiac envelope, including respective nodes thereof, a given distance and direction to define a perturbed geometry of the cardiac envelope, in which the perturbed geometry includes respective nodes; and
compute reconstructed bipolar electrical signals on to the nodes residing on the primary geometry of the cardiac envelope based on the electrical data and the geometry data, including respective nodes of the primary geometry and respective nodes of the perturbed geometry.
