心电图作为一项重要的临床检查技术,其应用久盛不衰已超过一个世纪,至今,它在临床中的地位丝毫未减,而且愈加广泛地用于心律失常、传导障碍、心肌梗死、心肌结构改变等方面的检查。众所周知,心电图的各种波形依赖于心肌细胞跨膜动作电位的特性、激动的扩散、容积导体的特性。在 As an important clinical examination technique, electrocardiogram has been used for more than a century, and its clinical status has not diminished so far. ECG is more and more widely used in arrhythmia, conduction disturbance, myocardial infarction and myocardial structural changes Other aspects of the inspection. As we all know, the various ECG waveform depends on the characteristics of myocardial cell transmembrane action potential, excited diffusion, volume conductor characteristics. in
