We have the case of a belligerent patient in a Connecticut hospital, who was brought in with atrial fibrillation brought on from a jump into an ice covered lake.

When he would not control himself, security tasered him, and it corrected his irregular heartbeat.

This is what a medical defibrillator does, and it can kill people too, just like the taser, though the defibrillator has not been called an instrument of torture by the UN’s Committee Against Torture

The use of TaserX26 weapons, provoking extreme pain, constituted a form of torture, and that in certain cases it could also cause death, as shown by several reliable studies and by certain cases that had happened after practical use.
