Due to the complexity and abstraction of ECG formation theory, teaching often becomes difficult to overcome. Toad electrocardiogram through the experimental methods and observation items to explore, making it a simple method, the result is intuitive, the effect is very good teaching experiment. The experiment vividly illustrates some of the basic problems of clinical ECG, is conducive to students’ understanding and mastery of ECG.
