We keep on improving our free heart rate validation and ECG analytical tool with new features and functionalities. HRT Analyzer v2.0.0 is now available with the following updates:

• Automatic updates – You’ll need to download and reinstall this version to enable them.
• Improved performance and smaller program size – The software has been rewritten for faster operation and easier expansion.
• Support for raw acceleration data (*.ACT) – You can now import ACT files for manual annotation, enabling calculation of respiratory rate and tail beat frequency.
• Zoom functionality – You can now zoom in on data for detailed inspection.
• Interval measurement – You can get a measurement between two points in milliseconds (ms) to estimate the duration of various intervals RR, QT, PQ and so forth within a record.
• Record search – Quickly locate specific ECG records in the Record ID dropdown list.
• Record comments – Add predefined or custom comments to individual records.
• Improved filter interface – Default and custom filters are now more intuitive to use.

The HRT Analyzer software is free and lets you process ECG data from *.HAT files, validate on-board algorithms and QI grading, calculate HRV (SDNN/RMSSD) automatically or manually, and measure QRS waveform amplitudes. It’s a powerful tool for both new and existing datasets. Some of these methods are manual, while others are automatic, and we continue to work on improvements.
