Description

The 3M™ Littmann® Master Cardiology™ Stethoscope is characterized by the best acoustic response in the Littmann mechanical stethoscope line; with a tunable diaphragm, dual lumen tubing, and a precision, ergonomically designed, stainless steel chestpiece. The 3M™ Littmann® Master Cardiology™ Stethoscope features tunable diaphragm technology—a 3M invention—that lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Unlike two sided models, there’s no need to turn over and reposition the chestpiece. Hold the chestpiece with light pressure to hear low frequency sounds; press a little more to hear higher frequency sounds. This time saving feature allows the healthcare provider to focus on the patient, while the non chill rim provides patient comfort.Headset tension is easily adjusted for head size and comfort by squeezing together or pulling apart the eartubes. Snap tight, soft sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove.Resilient next generation tubing retains its shape and flexibility even after folding tightly into a pocket. It provides longer stethoscope life due to improved resistance to skin oils and alcohol, and is less likely to pick up stains. Next generation tubing is not made with natural rubber latex, a benefit to sensitive medical professionals and their patients. And, to play its part in the protection of human health and the environment, the next generation tubing does not contain phthalate plasticizers.Put the power of improved listening in your pocket with the Littmann Learning App. This powerful app is designed to help users better recognize benign and pathological heart sounds, murmurs, and lung sounds. It reinforces learning by offering self-directed learning modules directly on your phone. You can download the free Littmann Learning App now from the App Store® or Google Play Store®.

    • Seriously, all the hype is true!
Color: Black Tube Style: Stainless Steel
Let me start by saying this is the first review I am writing for any product. I just had to write this one! Firstly, I must commend amazon for their excellent delivery service, my package took just about 11 days to be delivered to Nigeria and all along, I was able to conveniently (and accurately) track it. At almost $200, it's an expensive stethoscope I must admit. At $321 (including shipping), it's the most expensive piece of medical equipment I own. The littmann master cardiology stethoscope is GORGEOUS! It has a polished stainless steel chest piece and an overall attractive design. I initially wanted the burgundy colour but it it wouldn't ship to my location so I had to settle for the black one which is still beautiful. For someone used to low quality stethoscopes, even the feel of the master cardiology is different. It screams quality and class. It's also considerably lightweight (I actually looked at the delivery guy like "are you sure there's master cardiology in here?") When I put it in my ears for the first time, and listened to my own heartbeat (over my clothes!), I couldn't believe my ears... the acoustic performance is just excellent. It has an adapter for pediatric auscultation and a single sided chest piece which allows one to listen to both high and low pitched sounds simply by applying pressure on the chest piece. As a young anaesthetist who'd be dealing with both adult and pediatric patients, I couldn't ask for more. It has got soft sealing ear tips that fit perfectly and cancel out ambient noise. In short, when you're looking for a high performance stethoscope which is worth every penny, look no further than littmann master cardiology. Excellent craftsmanship, littmann! ... show more

    • Noticeable difference from Master Classic II
Color: Black Tube Style: Stainless Steel Black Finish
Compared to my trusty Littmann master classic II which I have had over the past 5 years, the master cardiology is a significant step up in terms of sound quality. I am no cardiologist, just a medical student, but I do find the sound insulation on the master cardiology to be noticeably better. The master classic had good isolation and will pick up just about everything this one does, but the cardiology scope is just another step up and feels like putting on a quality pair of isolation headphones. I have had both stethoscopes with me for the past 2 weeks on wards for comparison, and the cardiology does a better job of shutting out ambient noise. This includes doing a better job of shutting out finger contact sounds on the actual chest piece. On the classic, it would pick up some friction sounds; on the cardiology, that is largely gone. For some of the larger patients with distant heart/lung sounds to begin with, this is a benefit. Secondly, the tuned diaphragm on the cardiology is better. The diaphragm itself has a larger diameter and the rubber casket around creates a better contact with the skin to create a better seal. There are some pinholes on the diaphragm which I suppose are there for air flow engineering reasons. Whatever the purpose, the tuneability is impressive. Just leaving the chest piece on on a supine patient (without pressing down at all), I hear clear low pitch sounds. A little pressure, and the higher pitches come out. Finally, the build quality between the two are on par. The tubing is a little thicker on the cardiology because it is a double lumen design. The chestpiece is a little larger on the cardiology and is a little more friendly to use as a reflex hammer because of a wider bezel. All in all, very satisfied with the product. The cardiology scope is way overkill if you're just going to be using it for vitals, but for hearing murmurs, crackles on a larger patient, it is definitely worth the price difference. ... show more

    • Some really good, some really horrible (I've never been a fan ...
Color: Plum Tube Style: Stainless Steel
Working as an R.N for over twenty years has given me many opportunities to use many stethoscopes. Some really good, some really horrible (I've never been a fan of disposable stethoscopes but they have a purpose). I started in healthcare using a large double sided 'scope, the classic "flip over for higher tones" type and as my expertise grew I found myself looking for that certain 'scope that would enable me to hear distinct heart sounds, tones and breath sounds thus improving my patient care. Thus I found the Littmann Master Cardiology stethoscope. This 'scope is heavy! Classically designed and a breeze to use. A gentle slight pressure on the diaphragm will allow one to hear even the slightest murmur in an infant's chest. There is no need to flip the bell over to auscultate adult breath sounds or heart tones; no need to worry about the bell mechanism stripping and spinning madly while you are trying to work! I used my first Littmann Master Cardiology stethoscope for almost fifteen years and then lost it in a house fire, along with a pediatric Littmann (a brilliant little 'scope to be sure). If you're unsure about which 'scope to purchase but want a stellar 'scope that will last a long time (sure diaphragms crack) get the Master Cardiology 'scopeTo replace it, I decided to get a Master Cardiology Stethoscope. A kit for various earpieces and diaphragms give the most discerning clinician what they need for patient assessment. A pediatric adapter is included. The high construction tubing conducts sound well. The diaphragm is solid in construction and ergonomic in design; with the rubber base it is more tolerated for patients to avoid the historically 'cold stethoscope'. The headset is comfortable. Its only limitation is that ocular auscultation for bruits is not ideal but nowadays, medical imaging is utilized to a great degree that this has been somewhat of a lost art. Listening for bruits in other locations is quite easy. This stethoscope is ideal for medical students, nurses, primary care physicians, and cardiologists. It has lasted a decade without issues. ... show more
