The isopotential mapping of the T wave in myocardial infarction was studied to find the characteristic abnormality. The negative area on the mapping at the deepest point of the negative T wave was located on the left precordial region or on the left precordial and lateral regions in cases with anterior or anterolateral infarction. In some cases with anterolateral or inferior infarction and in cases with high posterior infarction, an extensive negative area was found on the left back region. In cases with inferior infarction, the negative area was situated on the lower area of the precordial region and/or back region. The ischemic area (the area of the abnormal repolarization) was determined by studying the relation of the zero line of the maps in normal subjects and cases with myocardial infarction. Finally, a comparison between the direction of the maximum T vector and the location of the ischemic area was made.
研究了心肌梗死时T波的等电位标测以发现特征性异常。在前壁或前侧壁梗死病例中，T波最深点处标测图上的负性区域位于左胸前区或左胸前及外侧区。在一些前侧壁或下壁梗死病例以及后壁高位梗死病例中，在左背部区域发现广泛的负性区域。在下壁梗死病例中，负性区域位于胸前区和/或背部区域的下部。通过研究正常受试者和心肌梗死病例标测图零线的关系来确定缺血区域（复极异常区域）。最后，比较了最大T向量方向与缺血区域的位置。
