VectBox Sync is a browser-based tool that computes a published VCG dyssynchrony index from 12-lead ECGs, enabling quantitative ventricular synchrony descriptors beyond QRS duration and morphology.
- Why it matters: Even with guideline-directed selection, many CRT patients do not benefit as expected, and QRS-based criteria miss the three-dimensional activation trajectory that VCG can capture.
- What they did: The application uses native digital ECG recordings (including matrices and common waveform formats), with optional manufacturer-PDF import and digitized numerical files; after optional preprocessing, users select a QRS interval and it calculates the dyssynchrony index versus a calibrated control cutoff.
- The result: It outputs VCG descriptors (voltage and speed integrals, loop angles, planarity), trajectories, synchrony-field maps, and multilingual PDF reports, supporting overlay comparisons across labeled conditions from the same session.
