Andrius Petrėnas

Project Senior Researcher at KTU Biomedical Engineering Institute

Andrius Petrėnas is a lecturer at KTU Faculty of Electrical and Electronics Engineering. In 2015 Andrius obtained a doctoral degree in technological sciences; since 2017 he is the Head of the Laboratory of Multimodal Biosignal Flows at the KTU Institute of Biomedical Engineering.

The main research direction of A. Petrėnas is the development of technologies for early atrial fibrillation arrhythmia recognition and the development and research of methods for characterizing the temporal distribution profiles of self-terminating episodes of arrhythmia.

The researcher is the winner of the first place of the Infobalt scholarship (2015), the laureate of the LJMS competition “Best Dissertation 2015” in the field of physical, technological, biomedical and agricultural sciences (2016), the laureate of the LMA young scientist scholarship competition (2019) , laureate of KTU’s most active young scientists competition (2018), laureate of the Kazicki Family Foundation prize competition (2020).

A. Petrėnas is also a reviewer of scientific journals (e.g. “Computers in Biology and Medicine”, “IEEE Transactions on Biomedical Engineering”).

Wearable technology for personalized identification and management of paroxysmal atrial fibrillation triggers – TriggersAF

Atrial fibrillation (AF) is the most common arrhythmia diagnosed in 33 million people worldwide. AF is a progressive disease that initially manifests as spontaneously intermittent paroxysmal episodes (PAFs). The project will develop a paroxysmal atrial fibrillation arrhythmia management system consisting of a wrist-worn device, server data analysis software, and a program for a smart device.

Methods for Long-term Unobtrusive Monitoring of Atrial Arrhythmias in Post-stroke Patients (AFterSTROKE)

During the project, signal processing algorithms, hardware and software system was developed for extended time monitoring of post stroke patients in unobtrusive way. A multisensory smart bracelet will serve as a main component to detect the presence of a co-morbidly dangerous disease – an atrial fibrillation arrhythmia. It is expected that the developed technologies for unobtrusive long-term monitoring of atrial arrhythmias will provide a better understanding of arrhythmia progression to more advanced stages, and will be useful for finding a causal relationships between arrhythmia progression and complications. The developed system have been patented in the State Patent Bureau of the Republic of Lithuania and described in three scientific articles with an impact factor.

Novel Technical Solutions and Biomarkers in Mobile Patient Monitoring

The project “New technical solutions and biomarkers for mobile patient monitoring” have been funded by the Swedish Institute Visby program, contract no. 00923/2011, duration 2011‐2013. Partners: Lund University (Sweden), St. Petersburg State Medical Academy (Russia).
