A system includes a display and a processor. The processor is configured to compute multiple forecasted local activation times (LATs) at different respective locations on cardiac tissue of a subject, by simulating a propagation of a physiological activation potential along the cardiac tissue with a particular portion of the cardiac tissue, which is currently conductive, being non-conductive. The processor is further configured to generate, based on the forecasted LATs, a forecasted electroanatomical map representing a forecasted state of the cardiac tissue following an ablation of the particular portion of the cardiac tissue, and to display the forecasted electroanatomical map on the display. Other embodiments are also described.

Forecasted electroanatomical maps for ablation planning

A method, including calculating locations of first sensors attached to a probe that has been inserted into a human patient, and calculating positions of second sensors attached to a sheath via which the probe is inserted. The method also includes calculating respective shapes of the probe and the sheath, to achieve a best fit to the calculated probe sensor locations and sheath sensor positions, while restricting the probe to pass through the sheath. The calculated respective shapes of the probe and the sheath are used to present an image of the sheath aligned with the probe.

Registering probe and sheath images on a display

Described embodiments include apparatus for use with a catheter. The apparatus includes a sheath configured for insertion into a body of a subject, and a sensor, coupled to the sheath, configured to detect an electric current passing through the catheter, when the catheter passes through the sheath and into the body of the subject. Other embodiments are also described.
