A now noninvasive platform for digitizing and analyzing electrophysiology (EP) signals offers healthcare providers higher diagnostic value.

The BioSig Technologies (Austin, TX, USA) PURE EP is a cardiac signal acquisition and display system engineered to assist electrophysiologists during electrocardiographic (ECG) and intra-cardiac procedures in order to diagnose and treat patients with abnormal heart rates and rhythms. By minimize noise and artifacts while acquiring high-fidelity cardiac signals, an EP exam's diagnostic value is increased, providing a clearer picture for interpretation and planning of subsequent catheter ablation treatments.

The proprietary hardware and software are designed to effectively eliminate noise, artifact, and baseline wander in real-time, exposing high-frequency micro-components in midst of large physiologic signals; fractionated atrial and ventricular electrograms; and high-frequency, low-amplitude signals such as the Purkinje potentials. Multiple review windows and filtering algorithms allow differential diagnoses during the cardiac ablation itself, reducing procedure length compared to current technology, which requires the clinician to step out of the control room and review ECG signals and apply filters to reduce noise and artifacts.

“Our PURE EP System is the culmination of many years of scientific research and business development efforts. It is our goal to provide tangible benefits to electrophysiologists and improve the current standards of EP procedures in the clinical setting,” said Kenneth Londoner, Chairman and CEO of BioSig Technologies. “We are excited to bring the advanced platform to the U.S. market.”

Electrophysiology comprises investigation of the electrical response characteristics of nerve and muscle. In the narrower sense, an EP study is a test performed to assess the heart's electrical system or activity and is used to diagnose abnormal heartbeats or arrhythmia. The test is performed by inserting catheters and wire electrodes, which measure electrical activity. The study is performed in an EP laboratory, usually under fluoroscopic guidance.
