Course detail

Cardiac diagnostics

FEKT-MPA-DVKAcad. year: 2021/2022

The course will guide students through the methods and techniques used in cardiac diagnostics. Students will gain insight into the anatomy and physiology of the heart and learn to record, filter and then interpret the manifestations of cardiac activity. The course is designed with emphasis on the interconnectedness of the topics described above.
