      Hear more with the new Littmann Cardiology IV Stethoscope. 

      Catching subtle sounds is critical to accurate patient assessment and diagnosis. The new Cardiology IV stethoscope is engineered to help you perceive the barely perceptible — the sounds that can tell you more about a patient’s condition.

      Designed for clinicians who require superior quality and exceptional versatility, the Cardiology IV stethoscope’s updated design and improved acoustics give you the ability to hear more of what you need to hear.

    The Cardiology IV stethoscope’s advanced features help you achieve more.

    • Littmann Cardiology IV Stethoscope better audibility.

      Better audibility of high-frequency sounds* helps you learn more about your patient’s condition.

    • Littmann Cardiology IV Stethoscope single-piece tunable diaphragms.

      Single-piece tunable diaphragms let you hear high and low frequency sounds on both the adult and pediatric sides of the chestpiece.

    • Littmann Cardiology IV Stethoscope pediatric side.

      Pediatric side converts to an open bell. Just remove the single-piece diaphragm and replace it with a non-chill rim.

    • Littmann Cardiology IV Stethoscope open bell.

      Open bell stays clear of dirt and debris by covering it with the small diaphragm.

    • Littmann Cardiology IV Stethoscope dual-lumen tubing.

      Dual-lumen tubing combines two sound paths in one tube, eliminating the rubbing noise of traditional double tubes.

    • Littmann Cardiology IV Stethoscope next-generation tubing.

      Not made with natural rubber latex or phthalate plasticizers, next-generation
      tubing lasts longer
      with improved resistance to skin oils and alcohol and is less likely to pick up stains.

    • Littmann Cardiology IV Stethoscope 7 year warranty.

      Seven-year warranty.
