Brief summary
ADInstruments HRV is a free Windows application for analyzing heart rate variability (HRV) from electrocardiogram (ECG) or arterial pulse recordings. It helps users detect and examine the timing differences between heartbeats, offering tools geared toward both human and animal research. The program is useful for researchers, clinicians, and anyone studying autonomic nervous system function or cardiovascular dynamics.
Core capabilities
- Interactive visualizations for inspecting beat-to-beat interval changes and trends
- Compatibility with ECG and arterial pulse input signals for flexible data sources
- A suite of analytical approaches (time-domain, frequency-domain, and nonlinear measures)
- Designed to support studies in both human subjects and animal models
- A graphical interface that simplifies navigation through recordings and results
Who should use it
This tool is particularly relevant for:
- Clinical teams and biomedical researchers seeking deeper insight into heart function
- Investigators performing autonomic nervous system or cardiovascular studies
- Laboratories that need a straightforward way to convert raw signals into HRV metrics
Platform, availability, and alternative
- Available at no cost and runs on Windows systems
- The HRV module provides multiple analysis techniques and configurable plotting options
- Recommended alternate: SHAREit (free)
How it helps your workflow
ADInstruments HRV simplifies the path from raw ECG/pulse traces to interpretable HRV outputs by combining automated analysis routines with manual inspection tools and detailed plots. This makes it easier to verify results, compare conditions, and present findings for both experimental and clinical work.
