January 16, 2017 — BioSig Technologies Inc. announced that the company’s Pure EP System, a novel cardiac electrophysiology (EP) signal acquisition and analysis system, was featured in the Journal of the American College of Cardiology (JACC): Clinical Electrophysiology. The article entitled “Novel Electrophysiology Signal Recording System Enables Specific Visualization of the Purkinje Network and Other High-Frequency Signals,” highlights the potential benefits of using the Pure EP System compared to a standard recording system. The study was completed by a team led by Samuel Asirvatham, M.D., at Mayo Clinic in Rochester, Minn.
The study focused on signals from the Purkinje network in the heart’s ventricles or lower chambers of the heart. Many ventricular arrhythmias are initiated in the Purkinje fiber conduction system. Ventricular arrhythmias are a major source of sudden death, which accounts for approximately half of cardiac mortality. This study proved that by using the Pure EP System during catheter ablation, doctors may be better able to treat these types of complex arrhythmias.
The Pure EP System is a surface electrocardiogram and intracardiac multichannel signal acquisition and analysis system engineered to assist electrophysiologists in making clinical decisions in real-time by acquiring and displaying high-fidelity cardiac signal recordings and providing clarity of data which may be used to guide the electrophysiologists in identifying ablation targets — areas of tissue to treat that otherwise create a heart rhythm disturbance (arrhythmia).
