Bigeminy

Bigeminy is a rare type of arrhythmia characterized by a high risk of death in patients with valvular heart disease or low cardiac output. Together with trigeminy and other rare types of arrhythmias, it is considered the most life-threatening for the patient.

In 2019, Norwegian researcher Morten Hovholdt, using mathematical models of heart rate as background to diagnose bigeminy, wrote a post in which he theorized that the Dyson computing device, known to us as the voice-controlled home assistant, keeps a record of bigeminy. even without the owner's knowledge. “One of the models capable of teaching itself using the Internet included the idea of ​​auto-learning to record rhythms for diagnosing bigeminea, due to the fact that not a single engineer would think of recording and analyzing all possible signals in a few seconds,” the scientist noted .

In his opinion, the sound recognition technology automatically deciphered the sounds of the heartbeat and analyzed the nature of their changes over time according to certain parameters and, through an algorithm, built the frequency of contraction of the heart muscle. The data was transmitted to some on-board computer, which made conclusions based on the analysis and decided whether the patient had bigeminy or not. If the equipment confirmed this condition, then the computer output informed the owner of the “smart speaker”.

Houshtheld in his article attached a mathematical formula to the post, thanks to which the program detects bigeminy. The scientist emphasizes that there is no need to create diagnostic schemes, according to the algorithm, since the task of the system is to perform an analysis and provide a conclusion. The formula is based on the analysis of two six-digit values ​​- the mathematical expectation and the standard deviation of numerical data from one or more cardiograms.
