The company’s work centers on improving the clarity and interpretability of intracardiac signals captured during electrophysiology procedures, with the goal of helping clinicians identify arrhythmogenic substrates and make more informed procedural decisions. Its primary offering is a signal-processing platform that combines proprietary hardware and software to amplify, filter and display intracardiac electrical activity with reduced noise and distortion.
