Since the advent of AppleWatch, although its heart rate monitoring function has been praised by Apple, the accuracy of this data has been questioned by many users. To this end, electronic Accessories maker AliveCor has launched an AppleWatch-specific strap, the Kardia Band, which allows AppleWatch's heart rate monitoring data to rise to the professional medical level.

According to the company's publicity, the Kardia Band is not an ordinary health product, but a person who has potential health problems in the heart.
According to Apple's official website introduction to Apple Watch heart rate monitor, it is not difficult to find that the technology used by Apple is the common PPG "photoelectric volume pulse wave tracing method", including Samsung Gear Fit, Fitbit Surge, Microsoft Band, etc. Heart rate monitor.
Their principle is to use a green LED light, with a photodiode to illuminate the blood vessels for a period of time, to measure the heart rate based on the absorbance of the blood. Therefore, their limitations are also obvious: the device needs to be close to the wrist, and the body hair should not be too strong, nor can it be measured when sweating.

The Kardia Band uses the EKG ECG measurement method to measure heart rate by recording electrical signals from heart fluctuations, which is the most commonly used and most accurate method in clinical practice.
The Kardia Band's strap is equipped with two sensors in front and rear. When users want to measure the ECG, they need to put their fingers on these two sensors.
You can then see the ECG data analysis in the Kardia Band App in AppleWatch.
