The Littmann Cardiology IV is a high-performance stethoscope designed for critical care and diagnostic precision. Its dual-sided stainless steel chestpiece features a 40% larger adult diaphragm and 60% deeper bell than the Classic III, making it easier to detect subtle heart, lung, and vascular sounds, including aortic stenosis, S3 gallops, and faint pulmonary anomalies.

Soft-sealing ear tips and a non-chill bell sleeve ensure comfort, while tunable diaphragms allow you to hear both low- and high-frequency sounds by adjusting pressure. Made in the USA with latex-free tubing, it is suitable for adult and pediatric patients in challenging environments such as ED, ICU, and cardiac units. Backed by a 7-year warranty, it is ideal for cardiologists, nurses, EMTs, and medical students requiring reliable, high-fidelity auscultation.
