The succinate dehydrogenase method of staining and the determination of the K+/Na+ ratio of heart tissue have been applied to forensic material as a tool for demonstrating early signs of myocardial infarctions. Both methods are controlled by a series of forensic cases dying from causes other than arteriosclerosis of the coronary arteries. Based on an analysis of normal material some factors influencing the K+/Na+ ratio are defined. It is concluded that the determination of the K+/na+ ratio shows more infarcts than the formazan method; however, the evaluation of the K+/Na+ ratio is difficult. The K+/Na+ determination is not recommended for routine use. A possible indication for the use of the K+/Na+ determination together with the formazan test could be cases of instantaneous death by accidents suspected to have been provoked by a fatal heart attack.
琥珀酸脱氢酶染色法以及心脏组织钾离子/钠离子比率的测定已被应用于法医材料，作为一种显示心肌梗死早期迹象的工具。这两种方法均由一系列死于冠状动脉粥样硬化以外原因的法医案例进行对照。基于对正常材料的分析，确定了一些影响钾离子/钠离子比率的因素。得出的结论是，钾离子/钠离子比率的测定比甲臜法显示出更多的梗死情况；然而，对钾离子/钠离子比率的评估存在困难。不建议将钾离子/钠离子测定用于常规用途。将钾离子/钠离子测定与甲臜试验一起使用的一个可能指征可能是怀疑由致命心脏病发作引发的意外猝死案例。
