What is a .HEA file?
HEA is a WFDB header describing a physiological recording such as an ECG.
- Did you know
- HEA headers accompany the signal files in PhysioNet’s research databases.
- A HEA file is the WFDB header that describes a recording’s channels, sampling rate and gain, paired with a separate .dat file holding the raw signal.
- Header and data files share a record name, as in the MIT-BIH Arrhythmia Database, where record 100 consists of 100.hea, 100.dat and 100.atr.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .HEA is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .HEA file
- Drag a .HEA file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
