Precision acoustics. Sleek design. Trusted performance.
The Littmann Cardiology IV Diagnostic Stethoscope Model 6186C is our most popular premium finish, featuring striking Alabaster White Satin Finish tubing paired with a deep black powder-coated chestpiece and binaurals for a bold, modern look. The Satin Finish tubing is designed to glide smoothly and resist catching on clothing, hair, and skin, helping you stay comfortable and focused throughout your day. At 27 inches, it rests comfortably around your neck and stays in place. Add same-day engraving for a crisp white imprint that stands out beautifully against the all-black chestpiece.
Whether you’re a physician, nurse, EMT, or medical student, the Cardiology IV delivers the performance and versatility needed to confidently assess both adult and pediatric patients.
Built for Clinical Excellence
Engineered for demanding environments like hospitals, ERs, and clinics, the Littmann Cardiology IV features dual-lumen tubing that eliminates noise interference and delivers clear sound directly to each ear.
It’s more than twice as loud* as comparable stethoscopes and excels at detecting low-frequency (below 120Hz*) sounds such as:
- Korotkoff sounds
- Mitral stenosis murmurs
- S3 and S4 gallops
