    Stethoscopes - Why WelchAllyn?

    Three key elements differentiate WelchAllyn stethoscopes from the competition: better performance, high quality, and more value.


    WelchAllyn Harvey and Elite cardiology stethoscopes are designed by the pre-eminent Dr. Proctor Harvey-the first and only "Master" of cardiology bestowed by the American College of Cardiology. Dr. Harvey designed these stethoscopes to accentuate the more important high-frequency ejection sounds, systolic clicks, and murmurs. Harvey and Elite stethoscopes also conform to American Heart Association (AHA) guidelines that indicate a stethoscope should include a diaphragm (for high frequency sounds) and bell (for low-frequency sounds). Many competitive brands have only a diaphragm. Unlike other brands, Harvey DLX and Elite also have adjustable binaurals, as recommended in the AHA guidelines.


    WelchAllyn cardiology stethoscopes are rugged, and are backed with warranties that typically exceed competitive models by two or more years.


    WelchAllyn Harvey and Elite stethoscopes are convertible, including both adult and pediatric diaphragms. It's like getting two stethoscopes for the price of one.

    What should I look for in a stethoscope?

    First and foremost, you want to be sure that the stethoscope fits correctly. If you can't get sound past the eartip to your tympanic membrane, all other features are unimportant. The more custom the fit, the easier the sounds travel to your ear. As a student, you must consider the versatility of the scope. The Harvey DLX and Elite, for example, adapt easily for pediatrics, and the bell is essential for cardiology.

    What is the advantage of a two-tube stethoscope?

    Two-tube stethoscopes, such as the Harvey DLX and Elite, provide an individual sound channel to each ear. This allows you to hear the subtle characteristics of heart sounds and murmurs more distinctly. The heavier tubing also filters out the distracting noise typical of a busy medical environment.
