title: [Isopotential map].
abstract: 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.
