Zargis® Cardioscan™

1 Based on findings from interviews, conducted by 3M in collaboration with Zargis Medical, with interested cardiologists at the American College of Cardiology (ACC) 57th Annual Scientific Session (March 29, 2008–April 1, 2008, Chicago, Illinois). N = 39.

2Clinical study conducted in 2005 by Zargis Medical in collaboration with The Johns Hopkins University School of Medicine. The study measured the accuracy of a group of primary care physicians in evaluating a set of 100 recorded heart sounds. The heart sounds were independently evaluated by each physician both with and without access to Cardioscan's reported findings. Clin Cardiol. 2008 Feb;31(2):79-83. The impact of computer-assisted auscultation on physician referrals of asymptomatic patients with heart murmurs. Watrous RL, Thompson WR, Ackerman SJ.
