Isopotential map, constructed from ECGs of many body surface electrodes, is an expression of body surface distribution of cardiac potentials at a moment. This ECG mapping technique, providing far more information than the conventional 12-lead ECG recordings, has proved moving multiple dipoles of the heart as electric power generator, and has clarified break through minimum indicative of the right ventricular epicardial depolarization. It is also utilized for diagnosis of right ventricular or posterior myocardial infarction, left ventricular hypertrophy, localization of accessory pathway in WPW syndrome, indication for intervention in acute myocardial infarction, identification of responsible coronary artery in angina pectoris, risk of ventricular tachycardia etc. Further information on the heart will be expected through this mapping technique.
等电位图由多个体表电极的心电图构建而成，它反映了某一时刻心脏电位在体表的分布情况。这种心电图标测技术提供的信息比传统的12导联心电图记录要多得多，已证实可用于移动作为电源发生器的心脏多个偶极，并明确了右心室心外膜去极化的最小突破指征。它还可用于诊断右心室或后壁心肌梗死、左心室肥厚、预激综合征旁路定位、急性心肌梗死的干预指征、心绞痛中责任冠状动脉的识别、室性心动过速风险等。通过这种标测技术有望获得更多关于心脏的信息。
