Title: Graphical User Interface (GUI) for Electrophysiology Studies


Invention: This technology presents a GUI in conjunction with software written for recording and storing signals related to electrophysiological studies. Once recorded, this data can be filtered, extracted, and mapped, in color, to visualize properties. Developed along with corresponding techniques used in rat electrophysiology studies, this technology may provide further insight before testing proceeds to human subjects.


Background: Nearly 2,000 electrophysiology labs in the U.S. and an expected 12 million atrial fibrillation patients by 2050 indicate that the market will continue to demand advanced EP devices that decrease ablation procedure times and improve success rates.



  • Electrophysiological research, development, and testing
  • Medical electrophysiological monitoring
  • Quality assurance amongst non in-vivo uses where electrophysiology is still relevant
  • Potential for implementation in non-medical avenues such as educational institutions



  • Ability to test new drugs for arrhythmia risk and/or prevention
  • Easy to use GUI enables better research performance in the lab with minimal training
  • Clinically relevant color maps visualize properties of the tissue
  • Enhances understanding of electrophysiological behavior
