Objectives:The ability to interpret a 12-lead electrocardiogram (ECG) is an essential skill in inpatient and outpatient settings. In medical school, this skill is generally taught during the Internal Medicine clerkship. Blended learning is a pedagogical tool that combines different modes of information delivery, models of teaching, and learning styles combining face-to-face learning sessions with online learning. The objectives of this study were to develop a curriculum using a blended educational model including lecture, focused educational videos, flipped classroom, and team-based learning to teach a systematic approach to ECG interpretation and enhance the ability of students to identify common and life-threatening electrocardiographic abnormalities.Methods: Between 2016 and 2019, 349 medical students from the University of Colorado School of Medicine received the blended learning curriculum, which included an introductory lecture followed by five 30-minute sessions. These sessions encompassed preclass videos and team-based learning in a flipped-classroom design covering critical concepts in electrocardiography. A sample of 64 students completed a survey evaluating confidence in ECG interpretation skills before and after the curriculum. All of the students completed a 17-item pretest and posttest. Results:The new curriculum improved learner confidence in ECG interpretation (Wilcoxon signed rank-sum test, P < 0.001). Postcurriculum test scores showed statistically significant improvement in all of the diagnoses tested (paired Student t test, P < 0.01), the most significant gains occurring in the life-threatening tracings of ventricular fibrillation and in ventricular tachycardia.Conclusions: Using a blended learning model with multiple educational modalities resulted in significant improvement in learners' performance and confidence in ECG interpretation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
