The autonomic nerves have been affecting the beating of the heart. The sympathetic nerves speed up the heartbeat, while the parasympathetic nerves slow down the heartbeat. Therefore, the human heart is not beating at a fixed speed but in a stable range.
In other words, the time interval between each heartbeat of our heart is not a fixed value, this kind of R-R interval change is called Heart Rate Variability or HRV,Therefore, HRV is also an indicator of the youthfulness of the heart.
The HR9 HRV with Pulse 5.3KHz heart rate monitor can fully meet the heart rate information requirements in different conditions, whether it is in the use of sports equipment, fitness training, or even the adjustment of the autonomic nervous system in yoga training.

The 5th Generation Bluetooth Strong Advantages You Must Know
Bluetooth 5.0 was released in June 2016. In addition to low power consumption, the effective transmission distance of the fifth-generation Bluetooth will be 4 times that of the 4.2LE version, and the transmission speed will be 2 times that of the 4.2LE version (the speed limit is 24Mbps). Therefore, the transmission speed is faster, the distance is longer, the signal is more stable and the power consumption is more efficient.
