The so-called “medical bracelet” can only help to monitor blood pressure and heart rate, but it does not necessarily achieve the heart rate and blood pressure required by the medical level.
First of all, the actual monitoring of the “medical bracelet” is the pulse, not the heart rate. In most cases, the heart rate and pulse are the same. You can also know the heart rate by monitoring the pulse. From this point of view, monitoring the heart rate through the bracelet is also OK. However, in the case of arrhythmia such as atrial fibrillation, the pulse rate and heart rate are inconsistent, and the pulse rate is less than the heart rate. At this time, the pulse value does not accurately reflect the true heart rate value.
Secondly, regarding the monitoring of blood pressure, the medically referred to blood pressure refers to the surface arterial pressure measured at the upper brachial artery at the same level as the heart. The electronic sphygmomanometer approved by the Hypertension Guidelines is also the brachial blood pressure value detected by the cuff method upper arm type electronic sphygmomanometer.
The “medical bracelet” is similar to the wrist-type electronic sphygmomanometer. The measured blood pressure value is only the wrist artery pulse pressure, especially when monitoring the blood pressure of patients with arteriosclerosis or poor peripheral circulation such as diabetes and hyperlipidemia. The results are still different from the true values of the upper brachial artery.
Of course, the “medical bracelet” is easy to operate and has good compliance. If it is not a professional medical monitoring method, it is only a general health monitoring. It has certain reference value for heart rate and blood pressure.
