Ultrastructural alterations of skeletal muscles after electric shock

Am J Forensic Med Pathol. 1985 Dec;6(4):296-300. doi: 10.1097/00000433-198512000-00005.

Abstract

The existence of tracks of electric current in the skeletal muscles was checked by electron-microscopic investigations in animal experiments on rats. Hypercontraction bands alternating with dilated sarcomeres and tumefaction of tubular apparatus and mitochondria with cristiolysis were established. The most severely expressed alterations were found in the vicinity of the electrodes and adjacent to the joints; they are thought to be caused by electrically induced tetanus and local hyperthermia. The forensic aspects of these findings are discussed.
