【摘要】 本文首次将分数维引入到心脏病研究领域中，确定了测量心电图维数的两种方法．选择了由无病到隐宓性冠心病到心肌梗这一病变过程作为应用例，发现其维数先增加后减小，即升维表示有病、降维意味着危险，同时发现心肌梗和冠心病有其各自的维数区间．从而为心脏病领域中的病变研究开辟了一条新路，并且为进一步开展心脏模型的混沌研究打开了一扇方便之门更多还原

【Abstract】 The paper introduces the fractal dimension theory into the reserch of heart diseases for the first time and comfirms two methods of measuring cardiogram dimensions. Moreover, the author takes the case from health to coronary heart disease and to myocardial infraction as an applying case. The author finds its dimensions increasing first then decreasing, i.e. increasing representing ill and decreasing representing danger. The paper brings out a new way in the field of heart desease research and opens a door to develop further the chaos research of heart model.更多还原
