Design of an autonomous device for long-term ECG monitoring

According to World Health Organization (WHO), diseases of the cardiovascular system are the most important factor that reduces the average life expectancy of a person. Many diseases are curable or controlled if diagnosed in a timely manner. The article is devoted to the development of an autonomous wearable device for long-term ECG monitoring. The need for prolonged ECG monitoring is due to the inability to detect certain cardiac diseases, in particular certain types of arrhythmia, during the standard daily (24-48 h) Holter monitoring. The main aspects of development are considered, the key components of the device are described and the electronic components base is proposed, the algorithm of the microprocessor software is also described. Technical requirements for the design of the device were established based on possible use cases and wishes from cardiologists. The obtained prototype has been approved, technical developments can be used in mass production.
