[New studies question the cardiac safety of conducted electrical weapons].

Conducted electrical weapons (CEW) were invented in the 1970s and are now widely used by more than 16,000 military and law enforcement agencies worldwide. Recent studies have sug-gested that a causal relation of cardiac arrest in humans and utilization of CEW may exist and cardiac capture and fatal arrhythmia have been documented in animal studies. We believe, based on current knowledge, that CEW use may have caused human fatalities. Users should be aware of potential serious side effects and be able to provide basic life support.
