Smart bracelet is an electronic device, does not belong to the medical device can not be used for clinical diagnosis. For patients with arrhythmia and heart failure, the error of measuring the heart rate simply through the smart bracelet is relatively larger than the results of the hand pulse and ECG methods, which can not provide a correct diagnostic basis for the clinic. Heart rate measurement by bracelet is more accurate. When measuring heart rate with a bracelet, the bracelet must be held close to the skin.
The heart rate value of Xiaomi phone watch is higher than that of the hospital
There is an error.
The heart rate value of Xiaomi Phone Watch has an error rate of about 2%, after all, it is not a professional heart rate measuring instrument, and it is normal to have errors.
Millet bracelet heart rate error: 1, please ensure that the back of the bracelet is clean, dry, and no foreign objects cover. Excessive sweating during exercise causes the watch to slide, and sweat obscures the light path, which may lead to inaccurate heart rate measurement. At this time, please dry the sweat and wear it tightly again.2. It is recommended to use a soft rubber strap so that the device can fit better with the wrist and the monitored data is more accurate.3. The human heart rate is not stable and immobile, even in a static state, the heart rate data will have a small range of fluctuations, and after strenuous exercise continuous measurement of a single heart rate, the value of the heart rate will be larger jumps due to the human body's own rapid decline in heart rate, which is also a normal phenomenon. This is due to the rapid decline of the body's own heart rate, which is also a normal phenomenon. When you have to stand, sit down, eat, drink water and other actions, the range of changes in heart rate data will also increase accordingly.4, regular exercise (such as running, walking, cycling, etc.) is easier to measure the heart rate, non-regular exercise (such as playing ball, free activities) may not be able to measure the heart rate, wrist strength type of exercise (such as lifting weights) may not be able to measure the heart rate.5, there may be hardware failures caused by the recommended before and after the millet service center The company's website has been updated with the latest information on the company's website, including its website.
Now the smart wearable devices can monitor the heart rate, however, this data is not accurate, there is an error, the cause of this error how to cause? That is to start from the principle of heart rate monitoring. Most of them use optical sensors, through the LED lights to illuminate the capillaries on the wrist, the sensor through the blood flow rate to calculate the heart rate, but this principle is susceptible to light, sweat, tattoos, so it causes errors.Suunto heart rate belt (orange) and BasisPeak (blue) heart rate data comparison (image from Tencent) foreign media tested a few models of the monitoring of the heart rate of the Smart wearable devices, and will data and PolarV800 and SuuntoAmbit3 two heart rate band obtained data comparison. The testers jogged wearing the watch and the heart rate bands, and then the final comparison was made. After the final comparison, the GarminForerunner225 had an error rate of about 10% in the middle of the run, when the heart rate was gradually leveling off, the Adidas miCoach sports watch had an accuracy rate of about 86% and an error rate of 14%, and the BasisPeak had an average error rate of 25%.
