… periodicity and regional variations in T-wave oscillations. TWA testing may yield positive (abnormal), negative (normal),… microvolt- and macrovolt-level TWA were considered to be distinct entities. However, studies from isolated guinea pig and rabbit hearts now suggest that these forms of TWA may differ only quantitatively …

… the U wave is not after the T wave, but is superimposed on the T wave, interrupting it. The polarity of the U wave may reverse (eg, become negative in mid-lateral precordial… the changes may be isolated to only a few leads Reciprocal changes and hyperacute T waves are not seen.

… Isolated T wave changes in the absence of ST changes are less frequently seen with acute ischemia, except for the presence of symmetrically-inverted T waves after an episode… myocardial cells . Severe, acute ischemia lowers the resting membrane potential (that is, makes it less negative, inside relative to outside charge), shortens the duration of the action potential, and changes …

日本小児循環器学会雑誌 29(6), 322-327, 2013
… 背景：心房中隔欠損（ASD）の心電図所見としては主に右脚ブロック（RBBB），孤立性陰性T波，胸部誘導のT波非連続性，右軸偏位（RAD），下方誘導（Ⅱ・Ⅲ・aVF誘導）のQRS notch（crochetage pattern）などが知られている．この研究の目的はASDの診断におけるcrochetge patternの有用性につき検討することである． 方法：① 2002～2012年の当院でカテーテル検査を施行したASD 59例を対象とし，その際 …
