No extra recording and no extra hardware. From the ECG you already capture, Cardiolyse derives more than 30 heart rate variability metrics, ECG codes and scores — from autonomic balance and stress to Heart Biological Age.
Upload recordings, follow their processing, and pull back results, signals and reports in the format your product needs.
Every request is authenticated with your API key in the X-Api-Key header. Short recordings can return results in one call; longer ones are uploaded asynchronously.
Device files and generic signal formats go in; structured data and ready-made reports come out.

We look at your devices, file formats, lead count and the results your product needs to show.
You receive an API key and start with the public documentation and your own sample recordings.
Your team connects upload, status and results, with our engineers on hand for questions.
Results appear in your platform, under your brand, with the reports and parameters you selected.
Yes. The full reference, with endpoints, parameters and example requests, is available at api.cardiolyse.com/docs. An API key is needed to send requests.
EDF, DICOM-ECG and device formats such as Mortara and DHeart, plus binary, CSV and JSON signals with their sample rate, resolution and lead count. RR intervals can be sent as JSON or CSV. If your device uses another format, tell us about it.
Synchronous upload returns the analysis in the same call and suits short recordings. For longer recordings, upload asynchronously and check the record’s processing status before fetching results.
Yes. You can request only selected parameters, retrieve a summary or the full analysis, and download PDF or Excel reports for the same record.
The API returns structured, standards-compliant JSON that maps into clinical systems. Additional standards-based output formats can be discussed for your integration.
Yes. We can set up evaluation access so you can run your own anonymised recordings. Contact us to get started.
