Load an ECG screenshot or scan, redact identifiers, and get an algorithmic read with measured evidence, the closest simulated pattern, and an optional private AI second opinion.
For self-study only. This is algorithmic image analysis, not a medical device or a clinical interpretation. Digitizing images is approximate (intervals ±20–40 ms, ST ±0.5 mm). Always defer to the formal read.
Privacy: the image is processed in this browser tab and is never stored. Nothing leaves your computer unless you ask for an AI read, which goes only through the local server on this machine to the provider you choose. Redact names, MRN, dates and locations first; the analysis and any AI request use the redacted copy.
Write your interpretation before looking. It stays in this tab only.
Red lines are what the algorithm read. If a lead is off, adjust the layout, scale or speed and analyze again. Click a finding to highlight its leads.
Compared on rate, intervals, axis and R, S, Q, ST and T in every lead.
Not available on this copy of the page. It works on the hosted site (with the passcode) and from the local server (cd local-ai && npm start, then open http://127.0.0.1:5177).
Enter the passcode you were given to use the AI second opinion.
