The article examines the experience of developing and applying interactive situational electrocardiography tasks while teaching Functional Diagnostics. It is an innovative teaching method aimed at developing clinical experience and improving practical skills of analyzing and interpreting electrocardiograms among  students and practitioners specializing in Functional Diagnostics, Cardiology,  Anesthesiology-Intensive care, Therapy, Emergency medical care, Geriatrics, and  General medical practice (family medicine). Interactive situational  electrocardiography tasks have been developed using electrocardiograms of real  patients. Interactive tasks contribute to a deeper penetration into the studied  material, make it easier to consolidate the acquired theoretical knowledge and form  stable practical skills of analysis and interpretation, which is important for the  training of highly qualified specialists.
