How does the Gudong heart rate monitor work

The Gudong heart rate belt may affect our heartbeat. Many of us have experienced irregular heartbeat. It is possible that there is a problem with our Gudong heart rate belt. This situation may cause great trouble to our normal limb activities. The problem of the Gudong heart rate belt is now also a key issue discussed in the medical community. So how can we alleviate the problem when we have the Gudong heart rate belt? Let us now understand the working principle of the Gudong heart rate belt.

Working principle:

1. The principle of a heart rate chest strap is to measure the periodic changes of cardiac current or electric potential in the skin through the electrodes on both sides of the heart rate strap. This current is so small that it is easily interfered with.

2. The first interference is other current noise signals in the skin. For example, tense muscles can also generate relatively large current noise. The way to prevent this is to keep the heart rate belt close to the heart, which is less than 2 cm below the nipple for men, or the lower edge of the breast for women.

3. The second interference is the noise signal generated by the displacement and friction between the heart rate belt electrodes and the skin. This interference is particularly noticeable during exercise, and is characterized by the numbers displayed on the heart rate monitor fluctuating. For this reason, conventional heart rate monitors are often designed with tire-like corrugations at the conductive rubber to increase frictional resistance and reduce movement. In terms of anti-interference ability in collecting heart rate signals, flexible fabric heart rate belts have great advantages over hard belts, because the flexible film electrodes can perfectly fit the contour of the human chest, greatly increasing the contact area between the electrodes and the skin. Secondly, like all smooth surfaces, thin film electrodes have strong adsorption to the skin after being wetted with water, and can be tightly adsorbed to the skin, greatly reducing the interference of electrical signals caused by friction during exercise.

4. The first category is 5.3KHZ low frequency. This is the internationally accepted heart rate transmission frequency. Most heart rate monitors and some fitness equipment in the gym, such as treadmills with heart rate displays and pedal machines, use this frequency to receive heart rate signals. The second largest category is 2.4GHZ high frequency, which uses 2.4GHZ radio wave transmission and often uses manufacturer-specific encryption and decryption technology to transmit heart rate signals. Its advantage is that it can alleviate some interference during signal transmission.

The third largest category is Bluetooth and ANT, which also belong to high-frequency transmission. The advantage is that there is an international standard Bluetooth protocol to follow, and the transmitter and the receiver can support each other as long as they follow the Bluetooth or ANT protocol. The more common Bluetooth heart rate monitors are Bluetooth 2.0 commonly used in Android systems and Bluetooth 4.0 SMART used in Apple IOS.

The above content introduces us to the relevant content of the Gudong heart rate belt. Now that we have understood these methods, when we encounter similar situations again, we can use the above methods for timely and effective treatment, so that we can recover our health as soon as possible and avoid the troubles of diseases. We also hope that everyone can strengthen physical exercise in their daily lives.
