What is ECG? What is PPG?

By  Joe Horner 2019-06-30 1011 0

Smart brand is very common now, data monitoring performance is becoming more and more professional, most of them have been used in ECG and PPG technology. For example, HUAMI AMAZFIT Verge 2, which was released lately, and AMAZFIT Verge smartwatch, which was released last year, both use this technology. So what is ECG, and what is PPG? Now let's talk about it.

What is ECG?

The electrocardiogram (ECG) is a diagnostic tool that is routinely used to assess the electrical and muscular functions of the heart.

 ECG

The heart is a two stage electrical pump and the heart's electrical activity can be measured by electrodes placed on the skin. The electrocardiogram can measure the rate and rhythm of the heartbeat, as well as provide indirect evidence of blood flow to the heart muscle.

This technology is applied to the smart bracelet to make the fitness tracker, which used to have a relatively single function, more professional.

What is PPG?

PPG is the use of photoelectric plethysmography (PPG) technology for the detection of human exercise heart rate, is an infrared nondestructive testing technology, applied in biomedicine.

 PPG

The detection of human exercise heart rate by photoelectric plethysmography (PPG) is an application of infrared nondestructive testing technology in biomedicine. It uses photoelectric sensor to detect the difference of reflected light intensity absorbed by human blood and tissue, records the change of blood vessel volume in cardiac cycle, and calculates the heart rate from the obtained pulse waveform. According to the characteristics of motion center rate detection, the purpose of this paper is to develop a low power consumption and multi-function real-time detection and analysis system of exercise heart rate by using advanced electronic technology and frequency domain analysis method. The sensitivity and reliability of the system are verified by exercise test.

Conclusion

The reason why the AMAZFIT Bip health bracelet is expensive is because it has the function of ECG+PPG dual heart rate measurement, in which PPG optoelectronics is responsible for testing heart rate and recording automatically throughout the day, and the system will automatically count and eliminate errors, thus obtaining the average level. On the other hand, ECG measurement is used for a single accurate test, which can fully evaluate the working status of the heart. The two measurement methods cooperate with each other, and the data are relatively more accurate and effective.
