Personal arrhythmia tracker

A group of students of Tomsk Polytechnic University is working on a personal arrhythmia tracker. This device will be designed as a cuff to be applied to an upper arm for daily monitoring of human heart’s activity and recording abnormal heart rhythms. The data will provide support to doctors in healthcare decisions.


‘In fact, our device is a portable electrocardiograph with a dedicated focus, i.e. it records arrhythmia or abnormal heartbeat.

The device is wrapped around your upper arm and records all electrical signals triggered by the contraction of the heart muscle,’

says Denis Dementiev, one of the developers, a master student at the Department of Precision Instrument Making.  


Heart’s activity will be recorded throughout a day and then sent to a smartphone via a special app which is also being developed by the students. Patients will be able to share this data with doctors so that they can base a diagnosis on comprehensive information. According to the developers, doctors will be able to directly receive the records of heart monitoring through a cloud service in the future.

According to a project leader and a TPU alumnus Arman Boyakhchan, the device will allow people monitor their heartbeat on their own and seek doctor’s advice only for a professional analysis of the collected data. Currently only medical institutions may use cardiac event recorders because the existing solutions are too expensive for ordinary patients.

‘Indeed, similar monitoring systems already exist and are used in hospitals, but they are not individual. That is, only medical institutions may purchase such equipment and patients use them in order of priority. We propose a device that everyone can buy without a doctor’s prescription so that people don’t need to wait for their turn. In addition, our arrhythmia tracker will be more affordable and convenient to use than its analogues. Its compact body and electrodes will be completely ‘sewn’ into the cuff.

The tracker will also cost about 7-8 thousand rubles, while the price of existing analogues is more than 100 thousand rubles,’

the developer explains.


TPU students have already assembled a fully working prototype. Now, the tracker should be modified to make it more convenient for everyday use. This task will be finished by the fall 2017. Later the students plan to start clinical trials at the Tomsk Research Institute of Cardiology.
