Experts to annotate
waveforms at scale

Waveforms are critical indicators of patient health, and can be leveraged to train predictive algorithms that detect heart, lung, neurological conditions, and more.

Our annotation platform enables clients to structure waveforms by both classifying features within the waveform and segmenting regions of interest. 

Use cases


Identify sharp waves, spikes or spike-and-wave complexes to understand epilepsy, seizures, stroke or tumor presence.


Tag patterns (e.g. P waves), size (e.g. T wave amplitude) and time ranges (e.g. QRS complex, R-R intervals) associated with cardiac rhythm disturbances, blood flow, and electrolyte changes.


Identify fiducial points and noise in the waveform to better understand volumetric changes in blood in peripheral circulation.
