Littmann Cardiology IV Stethoscopes

Choosing a Cardiology Stethoscope for Clinical Practice

The Littmann® Cardiology IV™ uses a dual-sided chestpiece with tunable diaphragms on both sides — eliminating the need to flip the chestpiece between adult and pediatric assessments. Clinicians adjust pressure to switch frequencies rather than repositioning, reducing examination time in high-throughput environments.

The smaller side converts from a tunable diaphragm to an open bell using the included non-chill bell sleeve — making the Cardiology IV™ particularly well-suited to family practice, emergency departments, and pediatric units where clinicians transition regularly between patient types.

Built for shared clinical environments

Next-generation tubing resists stains and retains its shape through years of clinical use. Unlike standard tubing that can crack or discolour with repeated sanitization, the Cardiology IV™ maintains its integrity through the cleaning protocols required in infection control environments — an important consideration in shared nursing unit settings.

Finish options & personal identification

Available in standard, special, mirror, champagne, and satin finishes, with select models featuring colored stems. Color-coded stems support department-specific equipment identification in facilities where stethoscopes are shared across clinical staff.
