The heart rate variability (HRV) of Midong Health Bracelet test is always low. What's the harm of being so low? Do you need to go to the hospital for examination?

HRV is an auxiliary index of physical health, and it is also an important index recognized by medicine to judge the ability of autonomic nervous activity to regulate cardiovascular system. Low HRV value indicates that the ability of major nerve activities to regulate cardiovascular system is low. Long-term low HRV indicates that the body is in a sub-health state at this time, and long-term low HRV will increase the probability of cardiovascular disease and sudden death. HRV and cardiovascular health index measured by Midong Health Bracelet are only used as a reference for physical health, not as medical equipment and methods for intervention, treatment and diagnosis of users' diseases. If you feel unwell, please seek medical advice promptly.
