Abstract

Background: Death by electrocution in the water, not always show specific phenomenon. Only about 55% show spesific sign. The diagnosis of death by electrocution needs cooperation of pathology, toxicology forensic, and investigating officer. Heart is the organ most vulnerable exposed in case of electric shock. We hope this research give significant influence medicolegal aspect to minimize the confusion diagnostic about death by electrocution. Purpose Determine the effect of exposure to electric current through fresh water medium towards histopathological changes of myocardial wistar rat. Method: This research used the post test only control group design. 30 Wistar rats were divided into 5 groups. Each groups contains of 6 Wistar rats. Group V,VI,VII,VIII each given with a electric current flows 1-30mA, 31-60mA, 61-90mA, 91-120mA were them passed through a water medium with voltage 220volt during 60 seconds. The cardiac were taken and stained using Hematoxylin Eosin. Data views are preparations of the ventricle and Reported a number of point hypercontraction. Results: The result of one way anova showed a significant difference of the number of point hypercontraction in Wistar rats between control and experimental groups (p=0,000). The result of post hoc showed a significant difference of the number of point hypercontraction in Wistar rats between each control and experimental groups (p=0,000 and p=0,001), but there were no significant differences between group V and group VIII (p=0.999.) Conclusion: There are images of heart ventricles hypercontraction due multilevel electrical expossure through fresh water medium. Keyword: Water conducted electrical current, myocardial histopatologic, ventricle hipercontraction of myocardial in wistar rats.
