Course detail

Cardiac diagnostics

FEKT-MPC-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.

Learning outcomes of the course unit

The graduate of the course is able to clarify and understand the methods and techniques used in cardiac diagnostics. 

Prerequisites

Work in the laboratory is conditioned by a valid qualification of "employee knowledgeable for independent activity" according to Vyhl. 50/1978 Coll., Which students must obtain before the start of teaching. Information on this qualification is given in the Dean's Directive Familiarization of students with safety regulations.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Teaching methods include lectures and practical laboratories. Course is taking advantage of e-learning systems. 

Assesment methods and criteria linked to learning outcomes

The evaluation of the course is determined by the decree of the course guarantor for the given academic year.
