Designed to support physicians in analyzing cardiac sounds for the identification and classification of suspected murmurs, Cardioscan connects wirelessly to the Bluetooth®-enabled 3M™ Littmann® Stethoscope Model 3200 for easy, real-time analysis.

• Cardioscan follows the standard auscultation protocol and integrates seamlessly with clinical workflow.
• Graphically displays shape and timing of suspected murmurs.
• Enables improved documentation of referral findings.
• Store results on your PC or online for serial studies.
• Review results when & where convenient and play recordings at slow speed to listen more closely.
• Helps you hone your own auscultation skills as you compare the diagnosis with software findings.
• May alleviate concern about misdiagnosing murmurs.
• May reduce unnecessary referrals- limiting stress for patients & their families.
• Use Cardioscan’s display or printed results to better explain your findings to your patients, allay their anxiety or convince them of the need to follow through with additional care.
• Cardioscan can also help document the complexity of auscultations.

• 95% of cardiologists indicated that Cardioscan would help primary care physicians improve detection of heart murmurs associated with heart disease.*
• According to a retrospective study published in Clinical Cardiology in 2008,** physicians using Cardioscan results reduced their false negative referral rates for heart murmurs by an average of 46% and reduced their rates of unnecessary referrals by an average of 41%.

• * 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.
• ** Clinical 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.

Proprietary Ambient Noise Reduction Technology

It cancels out, on average, 85% of ambient background noise that can interfere with the auscultation experience, without eliminating critical body sounds. So you’re much less likely to miss the sounds you need to hear in noisy work environments. A full 13% better than previous models.

Acoustic Seal Eartips and Tubing

Not only do our patented 3M™ Littmann® Snap Tight Soft-Sealing Eartips provide a comfortable fit, they also create an excellent acoustic seal, as does our tubing. It means a tighter seal from ambient noise entering through tubing and eartip connections.

State-of-the-Art Sound Sensor

Built to stringent specifications, it provides a life-like 3M™ Littmann® sound experience similar to a high-end cardiology stethoscope. Positioned at the base of the tubing, the sensor brings the sound more naturally to your ears.

Frictional Noise Reduction Technology

A number of changes in the chestpiece help reduce handling noises compared to earlier electronic stethoscopes. It’s less distracting. So it helps you focus more on what you need to hear.

Up to 24X Sound Amplification

Extra listening power for those times when you need it; may be helpful when a heart, lung or body sound is especially faint; when a patient is obese; or when a patient’s clothing restricts your listening experience.
