(Replacement) HRV Chest belt for HRV Sensors: Comfort & Hygiene

A high-quality HRV chest belt is the prerequisite for error-free signal transmission. Since the strap is worn directly against the skin, it is a wear-and-tear item that can lose elasticity and conductivity over time due to sweat and regular washing. With our original replacement chest strap, you ensure that your HRV measurements remain ECG-accurate without having to purchase an entirely new sensor.

Maximum Signal Quality through High-End Electrodes

The electrodes embedded in the textile band are the heart of the data transmission. Our replacement strap features highly conductive contact surfaces that precisely capture the smallest electrical impulses of your heart. This is crucial for the Lifefire® spectrogram, as even minimal signal interference could distort the analysis of the R-R intervals. A fresh strap guarantees the stability you expect during long-term and sports measurements.

Universal Fit and Exceptional Comfort

The HRV chest belt is designed for maximum discretion in everyday life. The soft stretch material is infinitely adjustable and adapts to any body shape without constriction.

• Skin-friendly textile: Optimized for 24-hour application.

• Secure snap connection: Fully compatible with the Autonom Health HRV sensor.

• Non-slip: Stays in the correct position even during intense movement or overnight rest.

Care Instructions for Long-Lasting Use

To maintain the conductivity of the electrodes and the elasticity of the fabric, we recommend regular cleaning. The HRV chest belt (without the transmitter module!) is machine washable. Experts recommend replacing the strap regularly (approx. every 6 to 12 months with intensive use) to permanently ensure the medical-grade data quality of your Autonom Health analysis.
