Cleveland Clinic Study Unable to Induce Ventricular Fibrillation

Cardiovascular Safety Profile of Electrical Control Devices and the Impact of Point of Delivery On Ventricular Fibrillation Thresholds Studied


SCOTTSDALE, Ariz., May 17, 2007 (PRIME NEWSWIRE) -- TASER International, Inc. (Nasdaq:TASR), a market leader in advanced electronic control devices, announced that a study by Cleveland Clinic reported that a standard electrical discharge from a TASER(r) X26 electronic control device (ECD) does not induce ventricular fibrillation.

The study used 13 anesthetized adult pigs according to Dhanunjaya Lakkireddy, M.D., an electrophysiology (EP) fellow at Cleveland Clinic during the study and now clinical assistant professor of medicine at the University of Kansas Hospital and a practicing Cardiac Electrophysiologist with the Bloch Heart Rhythm Center. It assessed the vulnerability for ventricular fibrillation (VF) induction by a standard five-second TASER X26 discharge at varying locations on the body surface in a pig model. VF was never induced with the standard one-time TASER X26 application at any of the five positions. The study concluded that even with the worst-case locations, with probes plunged fully towards the heart, the researchers were never able to induce VF in 34 kg (76 lb) pigs at standard strength and duration of application.

"A standard five-second TASER ECD application is unlikely to cause life-threatening arrhythmias, at least in the normal heart, irrespective of the position of application," said Dr. Lakkireddy.

"This research provides vital data on the electrical current of TASER technology," said Rick Smith, CEO for TASER International. "The study sheds light on the often speculated issue of probe location as it relates to VF concerns during a TASER X26 application. Although this debunks past speculation in the media concerning this issue we continue to encourage and support further research into this technology," concluded Smith.

This study was presented as a featured abstract at the Heart Rhythm Society 28th Annual Sessions in Denver, CO last week. The study's research poster is available at: http://www.abstracts2view.com/hrs07/view.php?nu=6361&terms.
