Queen's Partnerships and Innovation is pleased to announce the issuance of U.S. Patent No. 11,991,095 entitled, "Sequential Mapping of Cardiac Arrhythmia without Fiducial Time Reference," on February 27, 2024 to Mohammad Shariat and Damian Redfearn. The patent relates to a method for generating a propagation and velocity map for cardiac wavefront propagation including cardiac arrhythmia, sinus rhythm, and paced rhythm. The propagation and conduction velocity maps may be used for one or more of diagnosing cardiac arrhythmia, localizing cardiac arrhythmia, guiding catheter ablation therapy of cardiac arrhythmia, and guiding cardiac pacing therapy.
