A pioneer study of the efficacy of the polygraph on subjects under the influence of Trasicor, a Beta Blocking agent, was conducted by the Scientific Interrogation Unit of the Israeli Police and the Department of Cardiology of the Ichilov Medical Center.
Abstract
Twenty volunteers underwent a series of 5 POT tests each; half with Trasicor administered beforehand and half with a placebo. Detection rate was highest for the placebo group, while that of the Beta Blocking group was still greater than chance. The GSR channel was found to be the most efficient identification index, but is also most vulnerable to the effect of Trasicor. The respiration channel indicates identification at a level better than chance, which is not effected by the Beta Blocking agent. The cardio channel was not found an efficient index of identification. (Author abstract)
