Electrodynamic discrepancy was observed in the hearts of 15 out of 144 patients with myocardial infarction who died on account of various complications. Autopsy revealed cardiac rupture with pericardial tamponade in each of the 15 cases. If the ECG shows no typical signs of a myocardial infarction, then with great probability an aortic rupture is present. The pathomechanism of electrodynamic discrepancy of the heart may be explained with the help of Laplace's law and "neuropraxia", "Afterload" and "preload" are reduced to practically nil, the tension of the myocardial walls falls, the effective work of the heart muscle stops and with the considerably lower oxygen requirement of the myocardium the bioelectric activity of the heart is still maintained for 12-30 minutes.
在144例因各种并发症死亡的心肌梗死患者中，有15例心脏出现电动力学差异。尸检发现这15例均有心脏破裂伴心包填塞。如果心电图未显示心肌梗死的典型征象，那么很可能存在主动脉破裂。心脏电动力学差异的病理机制可用拉普拉斯定律以及“神经失用症”来解释，“后负荷”和“前负荷”实际上降至零，心肌壁张力下降，心肌的有效工作停止，而心肌对氧的需求大幅降低的情况下，心脏的生物电活动仍可维持12至30分钟。
