Physiology of ECG: A ‘Mannequin’ based approach for first year medical students

Abstract

Introduction: Physiology, the foundation for medicine, learnt by animal experiments have long been replaced by computer or simulation or mannequin based teaching. Mannequin usage for Electrocardiogram (ECG) session, with case based discussion session provides hands-on practice to first year medical students without compromising patient care and safety. Case discussion improves critical thinking in a team. Objective: To evaluate the perception and learning for physiological basis of ECG using mannequin based teaching approach for first year medical students. Method: Observational, cross sectional study of first year student from 2017-18 batch in Sumandeep Vidyapeeth. Theoretical aspect of ECG was explained by interactive lecture series followed by 3hours practical session in groups (25 students per group) on “Heartsim 200” mannequin with clinical cases based on variation in ECG parameter as per cardiac disorder. Result: Statistically significant learning outcome was observed from pre-post analysis. Students agreed to a have a deeper understanding of the concepts, other than enjoyed this learning activity. Usage of this type of activity for other clinical practical session was strongly agreed by majority of the students. Although, limited time and large group of students were highlighted as limitations for the study. Conclusion: Mannequin is a useful learning tool for deeper understanding of clinical cases and practical during first year of medical teaching program.
