“…Numerous studies have been carried out in an attempt to clarify the internal signs of the passage of electric current. These findings were confirmed by conducting the experiments on animals , histological investigations , immunohistochemistry , biochemical analysis , and SEM/EDX analysis on humans. Our study focused on possible cardiac histomorphological changes in high and low electrical voltage deaths.…”

In electrocutions, death may be caused by alterations in the heart conduction system provoking ventricular fibrillation. This study aims to identify histological cardiac markers of high-and low-voltage electrocution. Two groups of decedents were evaluated: group A included 14 fatalities caused by high-or low-voltage electrocution and group B (control) included 14 fatalities due to other traumatic or disease causes. Myocardial sampling with microscopic examination was performed on all the hearts using the hematoxylin and eosin and Masson's trichrome stains to investigate morphological characteristics that could indicate the damage caused by high-and low-voltage electrocutions. Interstitial myocardial hemorrhagic infiltration was the only differentiating finding, which was shown only in high-voltage electrocution. This pathological finding has not been previously reported, and it may be specific to high-voltage electrocution deaths. Further studies are warranted.

“…The echocardiogram revealed a left ventricular apical hypokinesia and the coronary arteriography confirmed undamaged coronaries. These findings prove that the cause of myocardial dysfunction is inconclusive to which the author provides three hypotheses: first, direct injury to the myocardium with resulting damage; second, myocardial contusion during cardiopulmonary resuscitation with subsequent haematoma formation in small coronary arteries possibly producing a myocardial infarction with normal coronary arteries; third, coronary spasm induced by electricity with resulting myocardial infarction [24].…”

“…direct, splash and ground strike). The direct type of lightning injury can result in "myocardial injury" (evidenced by a significant increase in CPKmb), depression of the ST-T tract, alterations in ventricular kinetics visible with echocardiography and also lengthening of the QT interval [20][21][22][23][24][25][26][27][28][29][30][31][32].…”

Cardiac pathology in death from electrocution

To better characterize the morphologic changes in electrocution, morphologic changes in the hearts of 21 subjects, who died instantaneously of electrocution, were compared to the hearts of decedents with different types of death. Sixteen myocardial samples per heart were processed for histological examination, and sections were prepared with a variety of specific stains. The frequency, location and extent of myocellular segmentation (stretching and/or rupture) of intercalated discs and associated changes of myocardial bundles and single myocells [myofibre break-up (MFB)] were recorded, quantitatively analysed and statistically evaluated. The frequency of MFB was maximal in cases of electrocution (90%). The findings show that MFB is an ante-mortem change and may be a distinct finding in electrocution.
