Technology

The Science Behind UHF-ECG

A 30-second confirmation when ECG morphology leaves room for doubt.

150–1,500 Hz Analysis

Standard ECG captures 0.05–150 Hz. UHF-ECG extends into the 150–1,500 Hz band, resolving depolarization timing that conventional recordings cannot detect.

Spatially Precise

High-frequency signal propagation is short, making UHF-ECG inherently more location-specific. Each lead captures local myocardial activation.

VED / e-DYS Metrics

Ventricular Electrical Delay provides non-invasive quantification of dyssynchrony — a key parameter for CRT optimization and pacing assessment.

QRS Morphology Classification

Automatic grouping of QRS complexes by morphology. Identifies the majority activation pattern and quantifies beat-by-beat variation.

Clinical Applications

Built for Electrophysiology

Quantitative dyssynchrony assessment for the procedures that need it most.

CRT Evaluation

Cardiac Resynchronization Therapy

Analyze recorded ECGs to quantify interventricular dyssynchrony and evaluate the effect of resynchronization on ventricular activation patterns.

Pacing Analysis

His Bundle & Left Bundle Branch Area

Assess ventricular synchrony from pacing recordings. Compare activation patterns across pacing configurations to evaluate capture and physiological activation.

Dyssynchrony Monitoring

Follow-Up & Research

Process follow-up recordings to track VED/e-DYS metrics over time. Evaluate changes in ventricular electrical activation across visits.
