Dear Mr. Smith,
In response to your inquiry about the effects of discharging two Tasers simultaneously
into an animal, I reviewed the data from the study we performed last year, This study was
detailed in an abstract and presentation to the Annuallntemational Couli::n:m;\: ofthe IEEE
Engineering in Medicine and BiolOgy Soeiety.
I found that in 3 of the 5 animals studied, we delivered the discharges of two Advanced
Tasers simultaneously a total of 10 times. These dogs weighed hetween 55 and 62 pounds, and
ti,e full power Advanced Tusers were used. We obs\:rved no \:pisodes of ventricular flhrillation
in these 10 episodes, which were all delivered to the chest wall vf the animals,
Our failure to induce ventricular fibrillation in these relatively small experimental
animals suggests that a similar discharge into an adult human would also be unlikely to induce
ventricular fihrillation.
If you have any fmther questions, please let me know.

Sincerely,

W7"- r? 7. £lJ
