Features: Since its clinical application in 1903, the electrocardiogram (ECG) has a century-long history. Its significant value in diagnosing cardiovascular diseases makes it a mandatory course for medical students. However, the ECG still falls under the category of an experiential discipline, presenting considerable challenges in teaching. Not only do students generally find it difficult to learn and understand, but teachers also struggle to teach it effectively. Over the decades, while ECG teaching professionals at various medical schools have continuously explored new approaches to help students grasp the basics of the ECG within limited teaching hours, many undergraduate and postgraduate medical students in clinical practice still feel overwhelmed and uncertain when faced with an ECG. After years of analysis and research, we have identified some shortcomings in the original teaching system, content, and methods: overemphasis on theory and neglect of practice; focusing on teaching diagnostic criteria for abnormal ECGs while overlooking the cultivation of comprehensive analytical skills. To overcome the challenges in ECG teaching, it is essential to implement new teaching methods, encouraging students to "practice to develop skills" by observing more ECGs, thinking critically, and generating reports. To realize this concept, we havely attempted a new teaching model in our instruction and compiled the "ECG Teaching Atlas" as a supplementary textbook. The ECG Teaching Atlas is divided into two parts: classroom teaching and self-study. The classroom content is organized into six sections, each serving as a teaching unit and synchronized with undergraduate teaching schedules. The overall content is arranged based on the analytical and thinking sequence of ECG diagnosis, completely different from traditional textbooks. Each teaching unit includes both teacher-led instruction and student practice. The book introduces differential diagnostic approaches and key diagnostic points through numerous charts and diagrams, making them easy to understand and remember. ECGs used in the classroom do not come with reference answers, creating suspense and encouraging active thinking among students. Meanwhile, the book provides normal ECG parameters and diagnostic tools as a "training wheel," enabling students to participate in interactive learning. This allows students to gradually master differential diagnostic key points and diagnostic standards through practice. The self-study section is divided into two levels (A and B), each featuring 30 and 40 carefully selected ECGs, respectively. Level A is primarily intended for undergraduate students to review and self-evaluate their classroom knowledge. Level B is suitable for postgraduate students, interns, and clinical physicians. The arrangement separates diagrams from textual explanations and reference answers to better cultivate independent thinking and diagnostic skills. The diagrammatic explanations focus on introducing diagnostic reasoning and differential diagnostic key points. For ECGs with multiple diagnoses, the clinical importance of each diagnosis is listed in order. The use of this textbook has significantly boosted students' learning motivation, fostering a positive atmosphere of teacher-student interaction in the classroom, achieving an effect of hands-on teaching. After two years of undergraduate teaching validation, students' ECG diagnostic skills have improved substantially. Therefore, we have revised the original trial textbook and officially published it.
