Although cardiac injury is known to be the leading cause of death in electrocution, the differential diagnosis can be challenging in forensic practice since the exact mechanism is poorly understood and there is lack of reliable markers. Thus, death due to electrocution may be classified as a negative autopsy. The serum levels of and myocardial immunostaining loss for cardiac troponins and heart-type fatty acid binding protein (H-FABP) are highly sensitive and specific biomarkers of ischemic myocardial damage and may have a diagnostic value in determining the myocardial injury or the cause of death due to electrocution. Due to this reason, a rat model is prepared to investigate these issues. Thirty-two Wistar albino female rats were included and randomly divided into four groups of eight subjects. Group A was the control group, and Group B, C, and D were exposed to electrical current of 110 volt (V), 220 V, and 600 V, respectively. Blood samples and the hearts were collected from the rats for biochemical and immunostaining analyses.
