The Firstbeat Bodyguard 3 (BG3) is a professional-grade sensor for short and long-term HRV measurements.
With Firstbeat Bodyguard 3 sensor you can select to record RR-intervals, ECG and/or 3D acceleration based on your needs. The sensor uses clinically approved medical electrodes to monitor ECG-based beat-to-beat heart rate data (RR-intervals). This is the “gold standard” for heart rate variability (HRV) monitoring used in clinical settings. The technology is reliable for all users, both during rest and in motion. Unlike optical sensors, accuracy is not dependent on, e.g., skin pigment or temperature, anatomy or motion state.
The device is lightweight and easy to use: Attach the device directly to the skin with two chest electrodes and the BG3 starts recording data automatically.
When purchasing the BG3 one (1) pouch of electrodes (30 pieces) are included. The data is uploaded to the computer with Firstbeat Bodyguard3 Exporter software (iOS, Windows), which is available free of charge. The Exporter software provides access to raw data files for ECG, RR-I and ACC in CSV format.
