Last week, the US Patent Office published a patent for Google's ECG device, which shows that the device allows users to record their ECGs anytime, anywhere, so that they can learn about them in sports or other situations. Your own level of heart activity.
ECG measuring equipment in most hospitals in China
Google's ECG device patent
In the hospital, the doctor puts a plurality of electrodes on the skin, attaches them to the skin, and then connects the positive and negative poles of the electrocardiograph galvanometer through the lead wire to record the electrical activity of the heart, and finally draws the ECG drawing. Today, with the development of the Internet, this old ECG recording method should obviously be eliminated, and Google's device can help users record ECG anytime, anywhere.
Since the electrocardiogram records electrical activity by measuring electrical signals at multiple points on the skin, it requires that the wearable device must be able to form a "lead," such as the arm, chest, and waist that must have contact contacts. Google's equipment has electrodes that come into contact with the skin, from bras, arm guards, to shorts, and the electrode contacts are elastically deformable and can be adapted to the skin like clothing.
The device can help athletes and patients record ECG at any time, and can send ECG data to the cloud server to record health status. Since the ECG can be easily measured by means of wristbands, watches and other devices like heart rate, it requires more contacts and more complicated lead methods, so the appearance of the device is more meaningful.
