According to the new study, smart speakers such as Amazon Echo and Nest Hub can be used to detect abnormal heart rhythms.
Researchers from University of Washington Has developed an AI-powered system that can enable smart speakers to accurately measure measurements typically performed by professional medical devices.
Researchers have described a system that detects vibrations from movements of the chest wall using sonar technology that are close to a standard smart speaker. The study used the developer version of a low-power Echo speaker and was able to pick up the vibrations of people within two feet of the speaker. The researchers said that newer, more capable speakers may be able to conduct tests remotely. According to the researchers, the technique can be used for future telephone appointments with doctors.

Currently, many wearable devices have added the ability to detect conditions such as heart arrhythmia and even A-fib. The Apple Watch, for example, was the first consumer device to have a medically approved electrocardiogram. This may negate the need for a wearable device, or any contact, if the technology improves.
“We have Google and Alexa around us in our homes. We mainly use them to get up in the morning or to play music, ”reports co-author Shyam Golakota, a UW computer science professor. “The question we are asking, can we use the smart speaker for something more useful.”
The researchers also described how the study worked: “The smart speaker emits 18–22 kHz inaudible sound and receives reflected echoes from the human body that encode sub-mm displacement due to the heartbeat Huh.”
The researchers said: “Compared to electrocardiogram (ECG) data, our system calculated the R-R interval for healthy participants with a mean heart rate greater than 12,280, and an average error of correlation coefficient of 0.929. In hospital. The average error for admitted cardiac patients was 30 ms of heartbeat over 5839 with a correlation coefficient of 0.301. “
