New Study: Tasers Much Stronger than Manufacturers Let On
The doctors and engineers consulted by the CBC to interpret the results determined the higher electrical current was enough to raise the risk of an irregular heartbeat to as much as 50 percent for those with existing heart troubles.
The risk level depends on various factors, including whether the heart lies between the Taser's barbs and how long the shock lasts. The risk would decline if, for example, the Taser's barbs fell off or didn't fully penetrate the skin.
Savard also concluded that multiple shocks from normally working Tasers posed up to a 5 percent risk of ventricular fibrillation, the abnormal heart rhythm associated with a heart attack.
