Abstract

Deaths associated with the use of electronic weapons almost always occur in young men involved in either civil disturbances or criminal activity. These situations are associated with high levels of circulating catecholamines and frequently associated with drug intoxication. The mechanism for these deaths is unclear. Clinical studies indicate that these high voltage electrical pulses do not cause cardiac arrhythmia. Acute stress cardiomyopathy provides an alternative explanation for deaths associated with electronic weapons and may provide a better explanation for the usual time course associated with taser deaths. Patients with acute stress cardiomyopathy usually have had an emotional or physical stress, have high circulating levels of catecholamines, present with an acute coronary syndrome but have normal coronary vessels without significant thrombus formation. They have unusual left ventricular dysfunction with so-called apical ballooning. This presentation has been attributed to the direct effects of catecholamines on myocardial cell function. Alternative explanations include vasospasm in the coronary microcirculation and/or acute thrombosis followed by rapid thrombolysis. Similar events could occur during the high stress situations associated with the use of electronic weapons. These events also likely explain restraint-related deaths which occur in independent of any use of electronic weapons. Forensic pathologists have the opportunity to provide important details about the pathogenesis of these deaths through histological studies and careful evaluation of coronary vessels.
