electrocardiography ecg interpretation fundamental skill medical students practicing medical professionals recognizing ecg pathologies promptly allows quick intervention especially acute settings urgent care needed however many medical students find ecg interpretation understanding underlying pathology challenging teaching methods varying greatly study involved development novel animations demonstrating passage electrical activity welldescribed cardiac pathologies showcased alongside corresponding live ecg traces webbased tutorial finalyear medical students aimed assess whether animations improved medical students confidence visualizing cardiac electrical activity ecg interpretation compared standard ecg teaching methods finalyear medical students imperial college london attended webbased tutorial demonstrating 7 animations depicting cardiac electrical activity corresponding ecg trace another tutorial without animations held act control students completed questionnaire assessing confidence interpreting ecgs visualizing cardiovascular electrical transmission tutorial interventionarm participants also invited webbased focus group explore experiences past ecg teaching tutorial particularly aspects found helpful could improved tutorial animations wilcoxon signedrank tests mannwhitney u tests used assess statistical significance changes confidence focus group transcripts analyzed using inductive thematic analysis overall 19 students attended intervention arm 15 79 completing pre posttutorial questionnaires 15 79 participating focus groups whereas 14 students attended control arm 13 93 completing questionnaires median confidence interpreting ecgs intervention arm increased tutorial 2 iqr 1530 vs 3 iqr 345 p001 improvement seen confidence reviewing diagnosing cardiac rhythms visualization cardiac electrical activity however significant difference intervention control arms pathologies p05 main themes thematic analysis ecgs complex topic past ecg teaching focused memorizing traces visualizations enabled deeper understanding cardiac pathology ecg learning requires repetition clinical links remain essential study highlights value providing concise explanations meaning pathophysiology behind ecg traces visually verbally ecg teaching incorporates relevant pathophysiology alongside vignettes discussions regarding investigations management options likely helpful students practices based solely pattern recognition although animations supported student learning key element tutors explanations animations may helpful supplement teaching instance openaccess videos
