Abstract：Objective To explore the advantages and teaching effectiveness of the hierarchical progressive teaching model in the teaching of electrocardiogram(ECG)interpretation ability of residents during standardized residency training.Methods Fifty non-cardiology residents participating in the standardized residency training in our hospital from July to December 2024 were selected as the research subjects.They were randomly assigned to the control group(n=25)and the experimental group(n=25)by lottery.Both groups received a total of 2 class hours of ECG knowledge review and 2 class hours of 5-step ECG reading teaching.The control group had 4 class hours of ECG case discussion,while the experimental group carried out 4 class hours of hierarchical progressive teaching relying on the ECG grading image library.A theoretical examination was used to evaluate the ECG interpretation ability of the two groups.Questionnaires were used to investigate the satisfaction with courses and the self-evaluation of ECG reading ability of the two groups.The mini-clinical evaluation exercise(Mini-CEX)was used to evaluate the clinical competence of the two groups.Results The accuracy rate and integrity of the test in the experimental group were higher than those in the control group;The satisfaction with ECG teaching and the self-evaluation in the experimental group were higher than those in the control group;The experimental group scored higher than the control group in communication skills,clinical judgment,humanistic care,and overall performance rating items;The above differences were statistically significant(all P<0.05).Conclusion The hierarchical progressive teaching is beneficial for improving residents'ECG interpretation ability and is a teaching model worthy of promotion.
