HRV Live
How the System Is Used
Flexible HRV monitoring for clinical practice, research, and experimental protocols
HRV Live enables professionals to observe autonomic nervous system dynamics continuously while physiological or experimental events unfold. By combining real-time HRV monitoring with event markers and detailed post-session analysis, the system allows clinicians and researchers to evaluate how HRV changes in response to tests, stressors, and interventions.
Monitoring Physiological Responses During Controlled Tests
HRV Live allows clinicians and researchers to observe how autonomic regulation changes during controlled procedures such as breathing exercises, cognitive tasks, or stress protocols. Event markers can be placed at key moments during the session, making it easy to compare HRV responses across different stages of the test.
Evaluating Stress and Recovery Dynamics
Continuous HRV monitoring makes it possible to track how the autonomic nervous system responds to stress and returns to baseline. By reviewing HRV trends and spectral dynamics over time, professionals can assess physiological recovery and resilience during extended observation sessions.
Research and Experimental Protocols
Researchers can use HRV Live to record long-duration physiological data while marking experimental events. After the session, recorded ECG and HRV data can be replayed, edited if necessary, and exported for further statistical analysis or inclusion in research reports.
Monitoring Responses to Interventions
HRV Live allows clinicians and researchers to evaluate autonomic responses to various interventions such as breathing techniques, relaxation procedures, pharmacological agents, neuromodulation, or therapeutic protocols. By placing event markers before and after each intervention, users can compare HRV parameters relative to a selected reference point and clearly observe physiological changes.

Software Interface
Clear and informative visual interface for real-time HRV monitoring and analysis
HRV Live provides a comprehensive visual environment for monitoring and analyzing heart rate variability. The software presents ECG signals, HRV parameters, and spectral data through multiple synchronized graphs and numerical displays, allowing users to observe physiological changes in real time and explore recorded sessions in detail. Its intuitive layout makes it easy to navigate between monitoring, event marking, and post-session analysis.
Real-Time HRV Monitoring Screen
The main monitoring screen displays raw ECG alongside multiple real-time visualizations of heart rate and HRV dynamics. Users can observe HR trends, time graphs of HRV parameters, LF–HF relationships, and a 3D spectral view simultaneously, providing a comprehensive picture of autonomic nervous system activity as it evolves during the session.
Event Markers for Protocol and Intervention Tracking
During monitoring sessions, users can insert event markers to identify important moments such as test stages, stimuli, or interventions. These markers appear as vertical lines across the time graphs, making it easy to correlate physiological changes in HRV parameters with specific events during the session.
Recorded Session Review and R-Peak Editing
Recorded sessions can be reviewed using the same rich graphical displays available during live monitoring, allowing users to examine ECG and HRV data in detail after acquisition. The review screen also supports visual editing of R-peak detection to help ensure accurate heartbeat interval analysis and reliable HRV calculations.
Multi-Parameter HRV Timeline Review
Recorded sessions can be analyzed through multiple synchronized HRV time graphs that display key parameters across the entire monitoring period. Event markers appear directly on the graphs, allowing users to quickly correlate physiological changes with specific moments or stages of the session.
Event-Based HRV Parameter Analysis
Selecting an event marker displays a panel with numerical values of HRV parameters calculated for the corresponding analysis window. This allows users to quickly evaluate autonomic responses associated with specific events while reviewing the full set of HRV graphs in the background.
Comparative Event Marker Analysis
HRV Live can generate comparative reports that evaluate physiological responses across multiple event markers. One marker can be selected as a baseline reference, while HRV parameters and bar charts for all other markers are displayed for clear side-by-side comparison.
Typical Session Workflow
A simple and structured workflow for HRV monitoring sessions
HRV Live is designed to support a clear and efficient workflow for professional HRV monitoring. From preparing the subject and recording ECG data to reviewing and analyzing the session results, the software guides users through each step of the monitoring process while ensuring accurate data collection and analysis.
1. Prepare subject and attach ECG electrodes
Prepare the subject according to standard ECG measurement procedures and attach disposable ECG electrodes. Connect the ECG sensor to the electrodes and verify that the signal quality is adequate for reliable heartbeat detection.
2. Select client record or create a new one
Choose an existing client record from the database or create a new record to store the session data. This ensures that all recorded HRV sessions are properly organized and associated with the correct subject.
3. Conduct a new session
Start a new monitoring session and observe ECG and HRV data in real time. Event markers can be added during the session to identify protocol stages, interventions, or other important moments.
4. Disconnect subject and dispose electrodes
After completing the session, remove the electrodes from the subject and dispose of them according to standard hygiene procedures.
5. Verify detected heartbeats if necessary
Review the detected heartbeats and visually inspect R-peak detection to ensure accurate heartbeat interval analysis. Corrections can be made if necessary.
6. Review recorded session
Examine the recorded HRV data using graphical displays and analysis tools. Event markers, HRV parameters, and comparative reports can be used to interpret physiological responses during the session.
