Abstracts of Two Human Studies On TASER Safety Presented At Cardiostim 2008 in France

Studies Find TASER Electronic Control Devices Have No Effect On Human Heart and Alleged Arrest-Related Deaths Not Caused by Electrical Stimulation


SCOTTSDALE, Ariz., June 27, 2008 (PRIME NEWSWIRE) -- TASER International, Inc. (Nasdaq:TASR), a market leader in advanced electronic control devices, announced that two abstracts reporting on human testing on the safety of TASER(r) electronic control devices (ECDs) were presented at Cardiostim 2008 during June 18-21, 2008 in Nice, France. Cardiostim is the premiere biennial international scientific event which brings together the most world renowned experts to review technical and scientific news in electrophysiology, surgery and imaging while presenting the most recent technological innovations and therapeutic advances.

The two studies involved human subjects and produced the following general results:


      Contrary to speculation that an electronic control device could
      induce ventricular fibrillation, the rhythm found in alleged
      arrest-related deaths was primarily asystole which is associated
      with drug overdoses and cannot be induced with electrical
      stimulation; and,

      Real time ultrasound showed that even when electronic control
      device probes are placed across the heart, the ECD electrical
      pulses have no effect on the human heart. This is in contrast
      with the result occasionally seen in research using small pigs,
      which have important physiological differences that make their
      cardiovascular system significantly more sensitive to
      electricity than in humans.

The two abstracts reporting data from human studies looking at the safety of TASER electronic control devices are:
