“The application of digital state of the art technology to the capture and analysis of heart sounds is opening a new era in cardiac diagnosis. The HD Steth has applied digital science to producing a superior auscultatory experience with suppression of extraneous noise and true fidelity of heart transients. Coupled with this technology is an ECG that is detected with the face of the listening surface. The display allows both recording of the heart sounds and their timing with the ECG. The permanent record of each patient will allow digital archiving for comparison and application of advanced digital technology for cardiac function analysis. As an academic cardiologist, I am assured that new observations of fundamental importance will emerge from this exciting technology.”

“ViScope Visual Stethoscope is a very elegant device and certainly has many different applications in research and clinically. In my role as a teacher it is important to help the novice time murmurs and sounds. It has been my experience is that the most difficult thing for most students is to time murmurs and distinguish whether they are systolic or diastolic and the ViScope is very helpful.”
Dr. Gabe Gregaratis, MD
Former Chairman of Cardiology at Letterman Army Hospital, San Francisco
“Primary care physicians and medical students will find the ViScope Visual Stethoscope device very useful for the interpretation of heart sounds and for increasing their diagnostic scope and accuracy for heart murmurs.”

“Patient monitoring with HD Steth contributes to the containment of major adverse effects such as heart failure and post-op cardiac effects.”

“Over the last 20 years I’ve been giving a standardized auscultation test to medical students and fellows and found that we don’t teach auscultation very well or at least the students don’t learn it well. Perhaps 30% of students are able to detect typical heart sounds and murmurs versus internal medicine residents get up to 40% and Fellows get up to 50-60%. With the focus on auscultation and making the physician a better physician, the ViScope Visual Stethoscope is very valuable. Like a renaissance, the ability to watch the phonocardiogram as you listen enables a concentration on what is being heard and what the sounds mean physiologically and pathophysiologically.”
Dr. Mel Chetland, MD
Former Chairman of Cardiology at Letterman Army Hospital, San Francisco
“I've been using the ViScope Visual Stethoscope intensely for about a year now and I don’t use anything else in auscultation. Having access to on-demand real-time digitized heart sounds as you listen has improved my own skills and teaching. Since using ViScope in my teaching rounds and clinic, I have come to appreciate the fidelity and sensitivity of the recordings and the ability to freeze the images for analysis and discussion. The battery life, reduced sensitivity to noise and variable frequency response has resulted in exciting and useful medical instrument.”

“The future of cardiology with healthcare reform is that there will be more restrictions to test ordering. The ViScope Visual Stethoscope promises to improve the diagnosis of aortic stenosis and the progression of it and reduce the healthcare costs especially on patients with moderate to mild aortic stenosis where routine follow-up echos are recommended.”

“HD Steth makes it simple to tag my high risk pediatric patients and screen for murmurs quickly and accurately at the point-of-care enhancing treatment. It moves the point of care from my office to…anywhere.”

“The ViScope device is very user friendly and the audio quality is excellent when compared to any imported stethoscopes available (Littmann, Tycos, and Welch Allyn etc)”
Dr. P. Madialagan
Additional Director, CGHS, Government of India
“The ViScope device has a good sensitivity in picking up Systolic, Diastolic and Continuous Murmurs and can be used as a good screening device for the detection of murmurs in the population at large even by paramedical workers and nursing staff.”
