Description

3M Littmann Cardiology IV Stethoscope – Black Finish | 2x Louder | Dual Tunable Diaphragm | ICU & Cardiology

The 3M Littmann Cardiology IV Stethoscope in Black Finish is the premier diagnostic stethoscope for cardiologists, intensivists, and advanced practice providers who require the highest level of acoustic sensitivity. Designed with a 40% larger chestpiece and 60% deeper bell than the Classic III, this stethoscope delivers superior low-frequency pickup, making it ideal for detecting subtle cardiac murmurs, S3 and S4 gallops, and other difficult-to-hear heart sounds. The dual tunable diaphragm allows clinicians to alternate between adult and pediatric modes without flipping the chestpiece.

  • Dual tunable diaphragm — adult and pediatric modes in a single chestpiece
  • 40% larger chestpiece and 60% deeper bell vs. Classic III for superior low-frequency detection
  • Dual-lumen tubing eliminates internal interference for cleaner sound transmission
  • Ambient noise reduction for accurate auscultation in noisy clinical environments
  • Designed for cardiologists, ICU/CCU clinicians, and advanced practice nurses

Cardiology-Grade Acoustic Performance:
The Cardiology IV sets the benchmark for acoustic stethoscope performance. Its enlarged chestpiece and dual-lumen tubing work together to maximize sound clarity and minimize signal loss — critical when detecting faint diastolic murmurs or assessing breath sounds in a noisy emergency department. The dual tunable diaphragm eliminates the need to physically remove and flip the chestpiece, streamlining the exam process in fast-paced critical care environments. Trusted by attending physicians, hospitalists, and cardiology fellows worldwide.

What's Included:
1 x 3M Littmann Cardiology IV Stethoscope (Black Finish), extra ear tips, extra non-chill sleeve
