ECG data file

Sampling rate (Hz) — optional

Compression mode

Drop CSV, TXT, or TSV ECG file here or choose a file above

Detected sample column—

Load a file to inspect its columns.

Sampling rate—

Enter it manually when known; otherwise the app will try timestamp detection and fall back to 500 Hz.

The parser detects CSV, TSV, or whitespace-delimited text, recognizes common ECG/sample column names, and scores numeric columns when headers are absent. If a timestamp/time column is present, its spacing is used to estimate sampling rate unless you enter one manually.

Load an actual ECG dataset and run the experiment.

Original vs reconstructed ECG

The plot is sampled down for display only. The exact-match test compares every reconstructed encoded sample with the original encoded sample.
