Bluetooth Enabled Littmann Stethoscope Allows Recordings for Analysis
The 3M Littmann Electronic Stethoscope Model 3200 features Bluetooth technology that wirelessly transfers heart, lung and other body sounds to software for further analysis. The company partnered with Connecticut-based Zargis Medical to develop two companion software packages exclusively for the Littmann Electronic Stethoscope Model 3200. Specifically:
• Zargis Cardioscan software easily pairs with the Littmann Electronic Stethoscope Model 3200 to guide the clinician through four main cardiac sites, then after approximately one minute, indicates whether or not the patient possesses a suspected diastolic or systolic murmur, and whether or not the murmur is suspected to be a class I indication for echocardiography referral.
• Zargis StethAssist software, included with the Littmann Electronic Stethoscope Model 3200, allows clinicians to visualize heart, lung and other body sounds, play recordings at slow speeds to hear more clearly, and save recordings for comparison to future auscultations.
• StethAssist and Cardioscan recordings and related patient notes are stored electronically and can also be sent to colleagues for a second opinion.
According to a retrospective study published in Clinical Cardiology in 2008, physicians using Cardioscan results reduced their false negative referral decisions for heart murmurs by an average of 46 percent and reduced their unnecessary referral decisions by an average of 41 percent.
