Abstract:
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.
