Abstract

The first attempts to measure and use the bioimpedance based information for medical purposes date back to a hundred years ago in 1924. Since then, the bioimpedance method has been always considered promising in medical diagnostics. Much has also been implemented in clinical practice, such as determining body composition and body fluid volume, monitoring and managing the hemodialysis process, and monitoring respiration and functioning of lungs. Monitoring and management of the cardiovascular system cannot be left out, especially when it comes to pacemaker implantation surgery.
But in reality, the implementation of the method has been much slower and more difficult than previously assumed. There are several reasons for this, which are also outlined in this speech. However, in recent years, bioimpedance sensors have found increasing application in cardiovascular surgery to monitor and assess the health and blood supply of heart tissue and other organs.
By measuring the electrical impedance of the heart at various frequencies, these sensors provide valuable insights into the physiological state and function of the organ. This talk will explore the principles and advancements in bioimpedance sensing technology specifically tailored for cardiovascular applications. Firstly, in implanted cardiac rhythm management devices, secondly in open chest heart surgery and during its aftercare, as well as in the postoperative period of tissue and organ transplantation and more general surgery.

Bio:

Mart Min is a distinguished professor and leading scientist at the Thomas Johann Seebeck Department of Electronics, Tallinn University of Technology, Estonia. He earned his Diploma Engineer’s degree in Electronics from the same university in 1969 and his Ph.D. in Measurement Science from Kyiv Polytechnic, Ukraine, in 1984. Dr. Min has also served as a guest scientist and professor at the Technical University of Munich and Bundeswehr University, Germany.

Dr. Min’s research focuses on electronic measurements and signal processing methods, particularly in medical applications. He has significantly contributed to developing rate-responsive cardiac pacemakers for US companies.

With an impressive publication record, Dr. Min has authored and co-authored over 250 papers and holds more than 40 patents. He has also edited several scientific books in biomedical engineering.

He is a senior life member of the Institute of Electrical and Electronics Engineers (IEEE) Instrumentation and Measurement Society and Engineering in Medicine and Biology Society. Additionally, he is a member of the International Committee for Promotion of Research in Bio-Impedance (ICPRBI).

Since becoming Professor Emeritus in 2017, Dr. Min has continued his research activities in biomedical electronics.
