Medico-legal autopsy cases were reviewed to detect myocardial changes induced by resuscitation methods. Myofibrillar degeneration (MFD) induced by resuscitation methods was classified into two types according to Luxol fast blue staining: contraction band (CB) and diffuse staining (DS). In the cases in which cardiopulmonary resuscitation had been performed, myocytes showing CB or DS formed small foci and were distributed in the papillary muscles, septum, and inner to middle layers of the myocardium. MFD induced by vasopressors was characterized by solitary distribution of degenerating myocytes that mainly showed DS and sometimes CB. When direct current countershocks had been performed, focal MFD in the subepicardial zone appeared to be a characteristic feature.
回顾法医尸检病例以检测复苏方法引起的心肌变化。根据卢塞尔坚牢蓝染色，复苏方法引起的肌原纤维变性（MFD）分为两种类型：收缩带（CB）和弥漫性染色（DS）。在进行心肺复苏的病例中，显示CB或DS的心肌细胞形成小病灶，分布于乳头肌、室间隔和心肌的内层至中层。血管加压药引起的MFD的特征是退化的心肌细胞单独分布，主要表现为DS，有时为CB。当进行直流电击时，心外膜下区域的局灶性MFD似乎是一个特征性表现。
