Wave propagation control enhancement

A medical method for wave propagation control enhancement, the method comprising:

• identifying local activation times (LATs) from electrical activity of tissue of a chamber of a heart captured by electrodes of a catheter inserted into the chamber and associating the local activation times with respective positions on the surface of an anatomical map of the chamber of the heart;
• computing a propagation of a cardiac activation wave over the anatomical map of the chamber of the heart from a start time in a cardiac cycle to an end time in the cardiac cycle responsively to the captured electrical activity, wherein the propagation of the cardiac activation wave is calculated using a sliding window of the local activation times;
• rendering a sub-region of the anatomical map to a display;
• selecting a time-bounded portion of the propagation of the cardiac activation wave commencing at a time after the start time, wherein the time after the start time is the earliest time the wave would arrive in the sub-region of the anatomical map;
• and
• rendering the time-bounded portion of the propagation of the cardiac activation wave on the sub-region of the anatomical map to the display.

A software product, comprising a non-transient computer readable medium in which program instructions are stored, which instructions, when read by a central processing unit (CPU), cause the CPU to:

• identify local activation times (LATs) from electrical activity of tissue of a chamber of a heart captured by electrodes of a catheter inserted into the chamber and associate the LATs with respective positions on the surface of an anatomical map of the chamber of the heart;
• compute a propagation of a cardiac activation wave over the anatomical map of the chamber of the heart from a start time in a cardiac cycle to an end time in the cardiac cycle responsively to the captured electrical activity, wherein the propagation of the cardiac activation wave is calculated using a sliding window of the local activation times;
• render a sub-region of the anatomical map to a display;
• select a time-bounded portion of the propagation of the cardiac activation wave commencing at a time after the start time, wherein the time after the start time is the earliest time the wave would arrive in the sub-region of the anatomical map;
• and
• render the time-bounded portion of the propagation of the cardiac activation wave on the sub-region of the anatomical map to the display.
