Heart Rate Variability (HRV) is a wellness metric that measures the variation in time between consecutive heartbeats. It provides insight into how your autonomic nervous system is responding over time.
With the Vagustim Premium subscription, you can measure your HRV directly within the Vagustim app using your smartphone's rear camera. No additional hardware is required.
For the best measurement:
- Use your phone's rear camera.
- Gently cover the camera completely with your fingertip.
- Keep your finger still throughout the measurement.
- Sit comfortably and avoid talking or moving.
- Use the measurement in a well lit environment, but avoid direct sunlight shining into the camera.
- Allow approximately 60 seconds for the measurement to complete.
For the most consistent results, try to measure your HRV under similar conditions each day, such as at the same time of day and while resting.
If you're unable to complete an HRV measurement, please refer to our HRV troubleshooting article or contact our support team for assistance.
