Key result
Omnipolar electrograms provide catheter-orientation-independent assessments of cardiac electrophysiology to better characterize myocardium and localize areas of scar or arrhythmias.
Why the study?
The study aims to explore omnipolar electrograms to better characterize myocardium through reintroducing electrogram direction-related fundamentals of cardiac electrophysiology.
Omnipolar electrograms offer a catheter-orientation-independent method to assess cardiac electrophysiology, potentially improving the localization of scars and complex arrhythmias.
May aid scar and arrhythmia localization in procedures; leaves open prospective validation before practice change.
Omnipolar electrograms (EGMs) make use of biophysical electric fields that accompany activation along the surface of the myocardium. A grid-like electrode array provides bipolar signals in orthogonal directions to deliver catheter-orientation-independent assessments of cardiac electrophysiology. Studies with myocyte monolayers, isolated animal and human hearts, and anesthetized animals validated the tenets of omnipolar EGMs. The combination of information from omnipolar-based activation vectors and voltages may aid in localizing areas of scar, lesion gaps, wavefront disorganization, and fractionation or collision during arrhythmias. The goal of omnipolar EGMs is to better characterize myocardium through reintroducing electrogram direction related fundamentals of cardiac electrophysiology.
