摘要
心电图产生原理是心电图学习的基础,其包含心电向量、投影和导联系统等知识体系.应根据三者的内在逻辑关系和教学规律选择适当的教学内容.课堂教学的第一步应讲授导联系统的知识链,第二步讲授心电向量的知识链,第三步讲授投影的知识链.通过三步层层深入、环环相扣的讲解,有助于学生理解和掌握心电图产生的原理和过程.
Electrocardiogram generation principle is the foundation of learning electrocardiogram and contains the knowledge system of the electrocardial vector,projection and lead system.Teaching contents should be appropriately selected according to the inner logic of the above three knowledge systems and the teaching rule.In classroom teaching,the knowledge of the lead system should be taught by step one,the knowledge of electrocardial vector should be taught by step two and the knowledge of projection should be taught by step three.The three steps help students understand and grasp the mechanism which causes the electrocardiogram more easily.
