December 9, 2022 — BioSig Technologies, Inc. an advanced digital signal processing technology company delivering unprecedented accuracy and precision to intracardiac signal visualization with its proprietary PURE EP System, Bioannounced that a peer-reviewed case report titled, “Confirmation of Acute Pulmonary Vein Reconnection with The Utilization of PURE EP’s High-Frequency Algorithm (HFA)” has been published in the Journal of Atrial Fibrillation & Electrophysiology. The publication is available electronically via the JAFIB-EP open access digital journal.
Co-authored by Roy Chung, MD, Clinical Cardiac Electrophysiologist at Cleveland Clinic and Zachary Koch, CCDS, CEPS, Clinical Director at BioSig Technologies, Inc., the case report describes a 65-year-old patient with a medical history of symptomatic and persistent atrial fibrillation undergoing pulmonary vein isolation (PVI). PURE EP’s HFA signal analysis was observed alongside the simultaneous signal anno New Primary Logo New Primary Logotation produced by a 3D mapping system. PURE EP™’s real-time HFA identified early local activation, providing a clear and precise location that served as the primary target for ablation therapy during the procedure. Results from the case study support the efficacy of PURE EP™’s HFA in identification of the pulmonary vein gap compared to the inferior annotation produced by the 3D mapping system.1
“This case study adds to the growing pipeline of clinical evidence validating the PURE EP System as an essential and valuable technology for today’s EP lab—particularly for challenging cases,” commented Gray Fleming, Chief Commercial Officer, BioSig Technologies, Inc. “We believe that these findings, along with other clinical applications we continue to explore in collaboration with the Cleveland Clinic, demonstrate PURE EP’s ability to set new standards in the field of electrophysiology.”
In October, the Company signed a master research agreement with Cleveland Clinic to explore expanded applications for its digital signal processing technology.
The proprietary High Frequency Algorithm (HFA)—a proprietary feature found only in the PURE EP System—reclaims the specificity lost within the blended data of the traditional bipolar wave. HFA enables electrophysiologists to apply specific near-field frequency data to the treatment of even the most complex arrhythmias. By removing unnecessary distractions, the PURE EP System with HFA preserves the value of cardiac signals and delivers clear, actionable insights to today’s electrophysiologist.
