We previously reviewed the Littmann Cardiology IV stethoscope and in this article, I have reviewed the superior 3M Littmann CORE Digital Stethoscope which boasts all features found in the IV model with more additional cool features.

This is a cardiology stethoscope that integrates with EKO CORE to make a smart detection tool with automated murmur detection, sound amplification, active noise cancellation, and wireless listening.

What’s special about cardiology stethoscopes?

Unlike other stethoscopes such as neonatal or pediatric stethoscopes, cardiology stethoscopes such as the model IV by Littmann are designed to hear heart, lung, and vascular sounds with great clarity. They have a tunable diaphragm that can be used to detect high-frequency or low-frequency sounds by simply alternating between light and firm pressure on the chest piece.
